a 6x^2 + x + 1
b 6x^2 – x – 12
c 6x^2 + 17x + 12
d 6x^2 – x + 12
5. Simplify this expression.
3x(2x^2 – 3x + 1)
a –3x^2 + 3x
b 6x^2 – 6x
c 6x^3 – 9x^2 + 3x
d 6x^3 – 6x^2 + 3x
6. Simplify this expression.
2x^3 + 3x^2 – x^3 – x^2 – 1
a x^3 + 2x^2 – 1
b x^3 + 4x^2 – 1
c 2x^2 + x^2 – 1

Use the FOIL method
First times First (First - 3)(First + 4)
Outside times Outside (Outside - 3)(3x + Outside)
Inside times Inside (2x - Inside)(Inside + 4)
Last times last (2x - Last)(3x + Last)
F * F = 6x^2
O * O = 8x
I * I = -9x
L * L = -12
Answer 6x^2 - x - 12

Why do you address this question to "Mr"?
Look at your responders. Females are perfectly capable of doing mathematics for themselves.
