Question

Angela simplified an expression to 4x-8x^2+7-2x^2.she decides the leading coefficient is 4. State whether you agree or disagree with Angela and explain why.

Answer 1

Leading coefficients are the numbers written in front of the variable with the largest exponent.

Consider the expression
`4x-8x^2+7-2x^2.` First, here you can see two terms
`-8x^2` and
`-2x^2` with x powered to second degree. Then

`4x-8x^2+7-2x^2=(-8x^2-2x^2)+4x+7=-10x^2+4x+7.`

The term with the variable with the largest exponent is
`-10x^2` and the leading coefficient is -10.

Answer: Angela's statement is not true.
