Question

How do you simplify (2x+5)(3x-12)

Answer 1

Simplifying 2x + 5 + -3x = 12 Reorder the terms: 5 + 2x + -3x = 12 Combine like terms: 2x + -3x = -1x 5 + -1x = 12 Solving 5 + -1x = 12 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
Add '-5' to each side of the equation. 5 + -5 + -1x = 12 + -5
Combine like terms: 5 + -5 = 0 0 + -1x = 12 + -5 -1x = 12 + -5
Combine like terms: 12 + -5 = 7 -1x = 7
Divide each side by '-1'. x = -7

Simplifying x = -7

Answer 2

By rearranging your terms!

1) First, remove the parentheses.
2x+5+3x-12

2) Next rearrange like terms together
2x+3x+5+(-12)

3) Now combine like terms!
2x+3x= 5x
5 +(-12)= -7

4) Final answer: 5x+(-7)
