Factor x^2+2x-24
x2+2x-24x2+2x24
Step 1
Consider the form x2+bx+cx2+bx+c. Find a pair of integers whose product is cc and whose sum is bb. In this case, whose product is -2424 and whose sum is 22.
-4,64,6
Step 2
Write the factored form using these integers.
(x-4)(x+6)(x4)(x+6)
 [x2  12  π  xdx ]  x2  12  π  xdx
