Question

(5x4 - 4x³ - 2x² + x − 19) − (x4 + 5x³ + 8x² + x + 5) evaluate !!

Answer 1

`p(x) = 4x^4-9x^3-10x^2-24`

Explanation:

I'm going to assume that your equation is
`(5x^4-4x^3-2x^2+x-19) - (x^4+5x^3+8x^2+x+5)`
So to evaluate it we need to simplify it. Find like terms and perform addition/subtraction on them.

`p(x) = (5-1)x^4 + (-4-5)x^3+(-2-8)x^2+(1-1)x+(-19-5) \\ \to p(x) = 4x^4-9x^3-10x^2-24`
