# How do you solve 2b2 plus 5b-35?

Assuming the equation is 2b 2 +5b-35=0, the quadratic formula is one way to solve this equation. It can't be factored easily. Do not confuse the "b" variable in the formula given with the "b" in the related link..
The values of a, b, & c are as follows to be used in the quadratic formula: a=2, b=5,… c= -35..
Placing these values in the quadratic formula gives: (-5+/- sqrt(5 2 -4*2*(-35)))/(2*2)..
This yields variable b = (-5+/- sqrt(305))/4 or (-5+17.46425)/4 & (-5-17.46425)/4 = 3.11606 & -5.61606 which are the two roots of the given equation. (MORE)

# 6 - b equals 5b plus 30 what is b?

im sorry i keep trying to set up the problem exactly how it is on my paper...but it wont let me... :/ the answer is b=-4 though

# Solve 5b plus 6 equals 32-8b?

5b+6=32-8b Since -8b contains the variable to solve for, move it to the left-hand side of the equation by adding 8b to both sides. 5b+6+8b=32 Since 5b and 8b are like terms, add 8b to 5b to get 13b. 13b+6=32 Since 6 does not contain the variable to solve for, move it to the right-hand side of the… equation by subtracting 6 from both sides. 13b=-6+32 Add 32 to -6 to get 26. 13b=26 Divide each term in the equation by 13. (13b)/(13)=(26)/(13) Simplify the left-hand side of the equation by canceling the common terms. b=(26)/(13) Simplify the right-hand side of the equation by simplifying each term. b=2 (MORE)

# 3a plus 3b-2a plus 5b?

# How do you solve bsquared plus 5b plus 1 using factoring using factor and sum?

b-squared plus 5b plus 1 is an expression: not an equation or inequality. There is, therefore, nothing that can be solved. Second, the expression does not have real factors. It makes no sense to use product (factor) and sum to find complex factors. Using the quadratic formula or completing the squa…res are far simpler. (MORE)

# 4a - 5b equals 7 4a plus 5b equals 17?

4a - 5b = 7 4a +5b = 17 From the first equation: 4a = 7 + 5b substitute this value in the second equation: 7 + 5b + 5b = 17 7 + 10b = 17 10b = 10 b = 1 Now,solve for a : 4a - 5(1) = 7 4a = 7 + 5 4a = 12 a = 3

# Solve this equation using addition method 4a subtract 5b equals 7 and 4a plus 5b equals 17?

# Is 2 plus 3 an algebraic expression?

It's more of an arithmetic expression, however, 2x 0 + 3x 0 = y would be algebraic.

# How do you solve 10a plus 5b?

You can't just solve one side of the equation. You always have to have both sides of the equal sign in order to manipulate the terms. If you have an equation like 10a + 5b=0, you can now solve for one of the terms (a or b), for example, b=10a/5 and a=-5b/10. Once you have solved for one term, you… can plug it back into the equation and solve for real values. In this particular equation, a=-1/2b so by putting any value in for b (say 2), you get a definite value for a (-1) but there are an infinite number of such values. (MORE)

Probably not much; of course you'll learn new things (just as you did in algebra), but they will be introduced gradually (just as they were in algebra).

# Will chemistry be hard for you if you got an A plus in algebra?

It may or may not be. Although mathematics is the language of science, some people can be good at mathematics/algebra but just can't visualize molecules. If you are good at algebra though, there is a much greater chance that you will find chemistry easier than someone who is poor at algebra.

# Will you have difficulties with chemistry if you got an a plus in algebra?

Well, you may still have difficulties, but it won't be because of the math. Most of the math in chemistry is algebra, but there's a lot of conceptual stuff as well. So take good notes!
