Best Answer

This is an incomplete quadratic equation. Drop the 0X, as it is superfluous.

4X^2 -25 = 0

X^2 =25/4

X = +/- sqrt(25/4)

X = +/- (5/4)

check

4(5/4)^2 -25 = 0

true

4(-5/4)^2 - 25 = 0

also true

You need two integers that multiply to give you -42 and when added (with addition rules) a positive one.
6 and -7 would fit the bill.
(x+6)(x-7)=>x^2+x-42
