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

MAXImum [283]

Answer:

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

Step-by-step 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.

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