Question

Find the sum and product of P (x)=2-x-xsquare ?​

Answer 1

Answer:

-1 and -2 respectively

Step-by-step explanation:

p(x) = 2 - x - x²

now to find the zeros of p(x)

then p(x) must be equal to 0

:. p(x) = 0

2 - x - x² =0

x² + x - 2 =0

x² + 2x - x - 2 = 0

x(x + 2) - 1(x + 2) = 0

( x + 2) (x - 1) = 0

:. x = -2 and x = 1

now sum = -1 and product = -2 ans
