Question

$p(x) = 2x ^{2} + x - 3 \: \: \: \: \: \: \: \: \: \: \: \: p(1)$
​

Answer 1

Step-by-step explanation:

p(x) = 3x³ - 2x² - x + 4

p(- 1) = 3(-1)³ - 2(-1)² - (-1) + 4

p(- 1) = 3 × (-1) - 2 × 1 + 1 + 4

p(- 1) = - 3 - 2 + 5

p(- 1) = - 5 + 5 = 0

p(- 1) = 0

Answer 2

Answer:

$2x {}^{2} + x - 3 \\ 2 {x}^{2} - 2x + 3x - 3 \\ 2x(x - 1) + 3(x - 1) \\ (2x + 3)(x - 1)$

I hope it helps you
