Question

Find the product: 6x(7x^2 + 5x – 6)

A)42x^3 + 30x^2 – 36x
B)13x^3 + 11x^2

C)42x^2 + 30x – 36
D)42x^3 + 5x – 6

Answer 1

C)42x^2 + 30x – 36

Answer 2

42x^3 + 30x^2 – 36x

Answer 3

\[42x ^{3} + 30x ^{2} -36x\]

Answer 4

You should multiply 6x by each of the terms within the bracket and add them together. For example, if the question was \[3x(2x^2+9x-4)\] you would get \[(3x)(2x^2)+(3x)(9x)+(3x)(-4)\]

Answer 5

42x^3 + 30x^2 – 36x
