Answer:
(x - 9)(x - 13)
Step-by-step explanation:
Find the factors of 117
1,117
3,39
9,13
Because 117 is positive, the factors are either both positive or both negative.
Find the pair which sums to -22. Inorder to get to -22, the factors must be negative.
-1 + -117 = -118
-3 + -39 = -42
-9 + -13 = -22
The correct factor is -9,-13. Put it inside the brackets.
(x - 9)(x - 13)
Answer:
Not a solution.
Step-by-step explanation:
4*5(9)+(4)(8)(9+4)=6(4)-10
4*45+32(13)=24-10
180+416=14
596=14
