I need help factoring the expression: \(a^2 + 10a - 24\)

Asked by alcatrazperez

Answer (3)

a 2 + 10 a − 24
= ( a − 2 ) ( a + 12 )
*Note : * Remember this formulas : x 2 + b x + c = ( x + p ) ( x + q )
when : p ⋅ q = c an d p + q = b

a 2 + 10 a − 24 = a 2 − 2 a + 12 a − 24 = a ( a − 2 ) + 12 ( a − 2 ) = ( a + 12 ) ( a − 2 )

The expression a 2 + 10 a − 24 can be factored as ( a + 12 ) ( a − 2 ) . This is done by finding two numbers that multiply to -24 and add up to 10. In this case, those numbers are 12 and -2.
