you should break the question down into different parts. So the first term is 4x multiplied by 2x^2
OpenStudy (anonymous):
which is?
OpenStudy (donnie1999):
8x^2
OpenStudy (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.
OpenStudy (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
OpenStudy (anonymous):
first is this the question? \[4x(2x^2 -7x +3) \]
OpenStudy (donnie1999):
ok so would it be 8x^2-14x+12x
OpenStudy (anonymous):
\[4x \times 2x^2\]
OpenStudy (anonymous):
is?

first, multiply the numbers, so 4 x 2 = ?
OpenStudy (donnie1999):
or 8x^2-28x+12
OpenStudy (donnie1999):
its 8x^2
OpenStudy (anonymous):
you have an extra x there
OpenStudy (donnie1999):
i thought i did so the answer is 8x^2-28+12?
