Question

please prove this sum
i want check​

Answer 1

Step-by-step explanation:

p(x) = 2x^2 - 3x + 7a

p(x = 2) = 2 (2)^2 - 3(2) +7a

0 = 2(4) - 6 + 7a

0 = 8 - 6 + 7a

7a = -2

a = -2/7

Now putting the value of a = -2/7

0 = 8 - 6 + 7a

0 = 8 - 6 + 7(-2/7)

0 = 8 - 6 -2

0 = 8 - 8

0 = 0

Hence, prooved
