2x+3x^2(4x-5)<br> please helpppp asap

Aliun [14]

Here's my step-by-step explanation:

We're just gonna factor.

If your teacher has spoken of FOIL, then he/she has probably said that it means First Outer Inner Last and that it helps with distributing problems like these.

Right, so let's get to it.

$2x+3x^2 (4x-5)\\2x(4x-5)+3x^2(4x-5)\\2x(4x) + 2x(-5) + 3x^2(4x) + 3x^2(-5)$

Can you see the FOIL method being spread out here? Let's keep going.

$2x(4x) + 2x(-5) + 3x^2(4x) + 3x^2(-5)\\8x^2 + (-10x) + 12x^3 + (-15x^2)\\12x^3 + 8x^2 - 15x^2 -10x\\12x^3 -7x^2 -10x$

Hope this helps, and let me know if I made a mistake! ^_^

The answer to this problem that is for homework

Tanzania [10]

Answer: 17/2

Step-by-step explanation:

1- <u>Add</u> up the numbers.

2- Cut 2 below the second fraction with 2 cubed, then 2 will be squared.

3- Solve the potentiation (2 squared is equal to four, because 2 * 2 = 4)

4- And, finally, compute 9/2 + 4. It will give 17/2.
