Answer:
(x + 9)(x - 7)
Step-by-step explanation:
We want to factorize [tex]x^2 + 2x - 63[/tex]
We need to find two numbers such that their product is -63 and they add up to +2. The two numbers are +9 and -7:
[tex]x^2 + 9x - 7x - 63\\\\= x(x + 9) -7(x +9)\\\\ = (x +9)(x -7)[/tex]
The complete factorization is (x + 9)(x - 7)
