Explanation:
The Given Polynomial is p(x) = 4x²-5k+3
Substituting the given value of x in Polynomial;
P(x) = 4x²-5k+3
P(x) = 4x²-5k+3
P(4) = 4(4)² - 5k + 3
P(x) = 4x²-5k+3
P(4) = 4(4)² - 5k + 3
P(4) = 4(16) - 5k + 3
P(x) = 4x²-5k+3
P(4) = 4(4)² - 5k + 3
P(4) = 4(16) - 5k + 3
0 = 64 - 5k + 3
0 = 64 - 5k + 3
0 = 67 - 5k
k = 67/5
