Question

If p(x) =x²-2x then find its value at (a) x=0 (b) x=2 (c) x=-2​

Answer 1

Step-by-step explanation:

p(x) =x²-2x

(a) x=0

p(0) = 0² - 2(0)

      = 0 - 0

      = 0

(b) x=2

p(2) = 2² - 2(2)

       = 4 - 4

       = 0

(c) x=-2​

p(-2) = (-2)² - 2 (-2)

        = 4 + 4 [ minus x minus = plus ]

        = 8

      Hope it is helpful. Take care.
