"x equals 0" is an equality, not an inequality. The question is, therefore, not consistent.
Solve this problem -x squared -40x- 80 =0
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.
10x=x 9x=0 x=0
Divide both sides by 8: m = 0
5 ^x = 0 5 = root square 0 5=0
8x2 + 16x + 8 = 0
2x(3x+6) = 0 x = 0 or x = -2
Solve using the quadratic formula
a2+30a+56=0 , solve for a Using the quadratic formula, you will find that: a=-2 , a=-28
4x2+50x = 0 4x(x+12.5) = 0 x = 0 or x = -12.5
y - 3 = 0 y = 3
By factoring. q2 + 16q = 0 q (q + 16) = 0 Now, either q = 0, or q + 16 = 0. Solve those two equations to get the solution.
8 x 0 = 4n 0 = 4n 0/4 = n 0 = n
3x2-9x = 0 x(3x-9) = 0 x = 0 or x = 3
144X = X2 144X - X2 = 0 (144 - X)X = 0 X = 0 or X = 144
9x2-9x = 0 x2-x = 0 x(x-1) = 0 x = 1 or x = 0
There are two answers in the solution set. To solve this we factor the left side to become 4a(a-4). This lets us get the 4. The other answers is 0. Set 4a=0 and solve for "a" and then a-4=0 and solve for "a."
5x2-2x = 0 x(5x-2) = 0 Therefore: x = 0 or x = 2/5
solve for y so if x + y = 0 then y = -x
If x squared -10 = 0 then x = the square root of 10
-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3
correct anser is C ; y=-45
x * x - 9 = 0 PEMDAS = Multiplication first. What multiplied it self equals nine? 3. So x = 3
p is obviously zero because any number x plus 0 equals itself.
