Question

find p o, p (1) and p (- 2)for the following polynomial p (x) 10 x- 4x square - 3​

Answer 1

Answer :

$p(x)=10x-4x^2-3 \\\\ => p(0) \\ p(0)=10(0)-4(0)^2-3\\p(0)=0-3\\p(0)=-3 \\\\ =>p(1)\\p(1)=10(1)-4(1)^2-3\\p(1)=10-4-3\\p(1)=6-3\\p(1)=3 \\\\ =>p(-2) \\p(-2)=10(-2)-4(-2)^2-3\\p(-2)=-20-4(4)-3\\p(-2)=-20-16-3\\p(-2)=-39$
