Multiply 3 plus 2x and 3-2x?
(3+2x)*(3-2x) = 9 - 4x2 [remember that (a+b)*(a-b)=a2 - b2]
What is A equation for -2x plus 8 equals 7x-10?
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
2 x plus 3 2x plus 6?
The equation 2x + 3 = 2x + 6 cannot be solved due to the "variable" cancelling itself out by moving to either side of the equal sign.
Multiply x plus 3 times x-5?
-2
What is 2x times x to the second power plus 9 simplified?
This depends where the brackets go. If the equation you want to simplify is (2x)(x2) + 9 then we just multiply the parts in the brackets. When you multiply powers you add the power, so this is 2x3+9 If the equation is 2x(x2+9) then we need to multiply each part of the bracket by 2x. This gives 2x3+18x
Multiply this number by 4 and subtract 39 to get twice the number plus 3?
4x-39 = 2x+3, 4x-2x = 42 x=21
How do you multiply x plus 2 x-3?
-1
What is 2x-1 plus 2x-1 plus 2x-1 plus 2x-1?
8x-4
When x3 plus 3x2-2x plus 7 is divided by x plus 1 what is the remainder?
(x3 + 3x2 - 2x + 7)/(x + 1) = x2 + 2x - 4 + 11/(x + 1)(multiply x + 1 by x2, and subtract the product from the dividend)1. x2(x + 1) = x3 + x22. (x3 + 3x2 - 2x + 7) - (x3 + x2) = x3 + 3x2 - 2x + 7 - x3 - x2 = 2x2 - 2x + 7(multiply x + 1 by 2x, and subtract the product from 2x2 - 2x + 7)1. 2x(x + 1) = 2x2 + 2x2. (2x2 - 2x + 7) - (2x2 + 2x) = 2x2 - 2x + 7 - 2x2 - 2x = -4x + 7(multiply x + 1 by -4, and subtract the product from -4x + 7)1. -4(x + 1) = -4x - 42. -4x + 7 - (-4x - 4) = -4x + 7 + 4x + 4 = 11(remainder)
How do you solve 1.3 plus 2.1 equals -2x-2?
1.3+2.1 = -2x-2 3.4=-2x-2 5.3=-2x (multiply both sides by -1) 2x=-5.3 (divide both sides by 2) x=2.7 Hope that helped!
What is the answer to 3x plus 2x-8x plus 2x?
3x + 2x - 8x + 2x = -x
-2x plus 5 13?
x = 256.5(-2x + 513 = 0)(x - 256.5 = 0) Divide both sides by -2(x = 256.5) Multiply by negative
