Question

I need help factoring for example: a^2 + 10a - 24

Answer 1

`a^2 + 10a - 24=\\ a^2-2a+12a-24=\\ a(a-2)+12(a-2)=\\ (a+12)(a-2)`

Answer 2

`a^(2) + 10a - 24`


`= (a - 2)(a+12)`


Note :
Remember this formulas :

`x^(2) +bx+c = (x+p)(x+q)`

when :

`p \cdot q = c\,\,\,\,\,\,and\,\,\,\,\,\,p+q =b`
