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
