Answer 1

I'll work on the first one soon....

Answer 2

For the second question answer -10 and -4
The second one factor two numbers that add to 14 and when you multiply the numbers you get 40. Are 10 and 4
(X+10)(X+4)
X+10=0
Subtract 10 on both sides
X=-10. Answer
X+4=0 subtract 4
X=-4
3rd question X= 2 and X= -9

Two numbers that add to -7 and multiply to -18 are -2+9=-7. -2 times 9=-18
(X-2)(X+9)=0
X-2=0 X= 2. X+9=0 X=-9
