Question

4. If p(x) = 2x3 – 5x+7 and q(x) = x2 + 3x – 2, then find 2p(x) + 3q(x).​

Answer 1

Step-by-step explanation:

$2p(x) = 4x {}^{3} - 10x + 14 \: \: \: \: \: \: \: (1)\\ 3q(x) = 3x {}^{2} + 9x - 6 \: \: \: \: \: \: \: \: \: \: \: \: \: \: (2)$

now by adding (1) and (2)

we get

$4x {}^{3} + 3x {}^{2} - x + 8$
