Question

Factor: x(to the second power)-3x-28

Answer 1

an equation of this form
\[ax^2+bx+c=0\]
can be solved using thethe quadratic formula\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]

Answer 2

Not every equation needs the quadratic formula, tests and teachers often set "easy" factorizations.

You need two numbers which multiply to give -28 and add up to -3 and put them in here:

(x )(x ) = x^2-3x-28

Answer 3

ans. (x-7)(x+4)
