## donnie1999 one year ago HELP ME PLEASE!!! Simplify the expression 4x(2x^2 − 7x + 3). I think the answer is 8x^2-7x+3

1. anonymous

you should break the question down into different parts. So the first term is 4x multiplied by 2x^2

2. anonymous

which is?

3. donnie1999

8x^2

4. mathstudent55

This problem involves the distributive property. You need to multiply the term outside the parentheses, 4x, by each term inside the parentheses, 2x^2, -7x, and 3.

5. mathstudent55

In order to multiply two terms, you need to multiply together the number parts, and multiply together the variables. For example: 2x * 4x = 2 * 4 * x * x = 8x^2 3x^2 * 6x^3 = 18x^5

@becjanel can you help me im confused

7. anonymous

first is this the question? $4x(2x^2 -7x +3)$

8. donnie1999

ok so would it be 8x^2-14x+12x

9. anonymous

$4x \times 2x^2$

10. anonymous

is?

11. anonymous

first, multiply the numbers, so 4 x 2 = ?

12. donnie1999

or 8x^2-28x+12

13. donnie1999

its 8x^2

14. anonymous

you have an extra x there

15. donnie1999

i thought i did so the answer is 8x^2-28+12?
