Question

Is this problem correct? If not how do you work it out?

Answer 1

We need to express this as a polynomial.

This is already expressed as a polynomial, but in a factorized form. We can express it in standard form by applying the distributive property:

`\begin{gathered} (2x+6)(4x-7) \\ 2x\cdot4x+2x\cdot(-7)+6\cdot4x+6\cdot(-7) \\ 8x^2-14x+24x-42 \\ 8x^2+10x-42 \end{gathered}`

Answer: 8x² + 10x - 42
