Hey!
so for A, you just distribute the 3x
the answer would be 3x^2 - 12x

For B what you want to do is the same thing but dont forget to distribute the negative as well!
Your answer would be -2x^3 - 3x^2

Hope this helps!

also since you are multiplying, here is a tip. When you multiply and you have 2 x's that are going to be multiplied like x times x, you want to add the exponent!

What is the solution to this system of equations?
amm1812

Answer:

Step-by-step explanation:

(i) x+2y=4

(ii) x=4-2y

(iii) 2x-2y=5  

substituting (ii) in (iii)

2x-2y=5

2(4-2y)-2y=5

8-4y-2y=5

-6y=5-8

-6y=-3

(iv) y=\frac{1}{2}              

substituting (iv) in (ii)

x=4-2y

x=4-2×\frac{1}{2}

x=4-1

x=3

∴ B.(3,\frac{1}{2})

HOPE IT HELPS YOU!!!!
