If (p(x)=x^2-14x+45) and (q(x)=x^2-14x+40), which statement is correct?
Answer and explanation
Correct answer: Zeroes of (p(x)) are rational and zeroes of (q(x)) are irrational real
For (p(x)), (D=196-180=16), while for (q(x)), (D=196-160=36), so both are rational. Therefore the listed intended contrast is not valid.
