factor x2+16x-36
factors are 18, 2
To find the factors of the quadratic expression x^2 + 16x - 36, we need to look for two numbers that multiply to give -36 and add to give 16.
One way to find the factors is to list all the possible factor pairs of -36 and check which pair adds up to 16. The pairs of factors of -36 are:
-36, 1
-18, 2
-12, 3
-9, 4
-6, 6
Since we need a pair that adds up to 16, the pair we are looking for is -6 and 6.
Thus, the factors of the quadratic expression x^2 + 16x - 36 are (x - 6)(x + 6).
