Question

P(x) = 5x^2 - 3x +7, find p(-1)​

Answer 1

Step-by-step explanation:

p(x) is divided by (x+1)

∴ p(x) = 5x²-3x+7

=> p(-1) = 5×(-1)²-3×(-1)+7

=> p(-1) = 5×1+3+7

=> p(-1) = 5+3+7

=> p(-1) = 15

SO, the value of p(-1) is 15.

Answer 2

Answer:

X=-1 , so the equation is

5×(-1)^2 - 3×(-1) + 7

5×1 + 3+7

5 + 3 +7

8 +7

answer is 15
