Verify that -0 and 4 are zero of the polynomial q(x) =x²- 4x |
|
Answer» Hence Verified Step-by-step explanation: Step 1 = first check by SUBSTITUTING X = 0(0 is a number which is neither positive nor negative) That is, Q(x) = x^2 - 4x We know that anything MULTIPLIED by 0 is 0 q(0) = 0^2 - 4(0) = 0 - 0 = 0 HENCE VERIFIED THAT 0 IS ONE OF THE ZERO OF THE POLYNOMIAL q(x) = x^2 - 4x Step 2 = Now check by substituting x = 4 That is, q(x) = x^2 - 4x q(4) = (4)^2 - 4(4) = 16 - 16 = 0 HENCE VERIFIED THAT 4 IS ALSO A ZERO OF THE POLYNOMIAL q(x) = x^2 - 4x |
