Answer:
1. x²+10x+16 = (x+8)(x+2)
2. x²-3x-28 = (x-7)(x+4)
3. I forget how to solve for number three sorry
Step-by-step explanation:
1. x²+10x+16
First find two numbers thats when you multiply it the answer is +16 we have 8x6=16 and 1×16=16 now which of the two is when you add it the answer is +10 we have 8+2=10 and 1+16=17 so the answer is 8 and 2 then (x+8)(x+2) always remember that it depends on the number if 8 is negative then it will (x-8) or if 2 is negative it will (x-2)
2. x²-3x-28
just like in number 1. find two numbers that when you multiply the answer is -28 we have -4×7=-28,-7×4=-28,-1×28=-28 and last is -28×1=-28 now from those four which of them when you add is the answer is -3 we have -4+7=3, -7+4=-3, -1+28=27 and -28+1=-27 so the answer is -7 and 4 then (x-7)(x+4)
Sorry if I don't have an answer of Number 3
