3x2+2(5x-7)?

Question

i cant figure out the answer.

Answer 1

First you must distribute the 2 into the parenthesis, so instead of (5x-7), it becomes 10x-14. Then look at the 3x2, which becomes 6. Then you add your two new numbers, 6+10x-14, which can be simplified to 10x-8.

Your answer: 10x-8

Good luck!

Answer 2

you wanna do parentheses first

5 x 7 = 35 and a positive x a negative is a negative so its ...

3x2+2x -35

6 + - 70 = -64

answer is -64

Answer 3

Assuming x is multiply, not a variable: -64.
