Question

The value of the polynomial ( ) 2 p xx x = − + 2 1 at x = 1 is ​

Answer 1

Answer:

p(−1)=2×(−1)−2×(−1)3+7 =−2−2×(−1)+7 =−2+2+7 =7. Thus, the value of polynomial for x=−1 is 7. Answered By. toppr. 2 Views.

Top answer

p(x) = 2x - 2x3 + 7 p ( - 1) = 2 × ( - 1) - 2 × ( - 1)3 + 7 = - 2 - 2 × ( - 1) + 7 = - 2 + 2 + 7 = 7 Thus, the value of polynomial for x = - 1 is 7 More
