Question

The value of the polynomial P(x) = 7x^4 + 3x^2 - 4, when x = - 2 is:

Answer 1

$Given \: P(x) = 7x^4 + 3x^2 - 4$

$If \: x = -2 \: then \: value \: of \: p(x) = p(-2)$

$p(-2) = 7(-2)^{4} + 3(-2)^{2}-4$

$= 7 \times 16 + 3 \times 4 - 4$

$= 112 + 12 - 4$

$= 112 + 8$

$= 120$

Therefore .,

$\red{ p(-2) }\green { = 120}$
