Question

I need the answer to questions 1, 2, 3, 4

Answer 1

Answer:

1 answer= (x-3) and (x+5)= d option

3 answer =c option

2 answer =x²+2x-15

now by splitting the middle term

we get

= x²+5x-3x-15

= x(x+5)-3(x+5)

= (x+5) and ( x-3)

4 answer

substituting (x+4) in equation it becomes-4

= (-4)²-2(-4)-24

= 16 +8-24

= 24-24

= 0

substituting (x-6) in equation it becomes +6

= (6)²-2(6)-24

= 36-12-24

= 0

so (x+4) and (x-6) are the factors of x²-2x-24
