Question

If P(x) =2x²-6x+8 ,the value of P(-1)​

Answer 1

Answer:

$2( - 1) \times ( - 1) - 6 ( - 1) + 8 \\ 2 \times 1 - ( - 6) + 8 \\ 2 + 6 + 8 \\ p(x) = 16$

p(-1)=16 or p(x)=16

Answer 2

Answer:

★Given:-

• p(x) = 2x² - 6x + 8

★ To Find:-

• Find Value of p(1)

★Solution:-

By Substituting -1 value in x,

➝ p(-1) = 2(-1)² - 6(-1) + 8

➝ p(-1) = 2(1) + 6 + 8

➝ p(-1) = 2 + 14

➝ p(-1) = 16

∴ Value of p(-1) = 16
