I hope it helps :))
Answer:
Step-by-step explanation:
hello :
here is two examples:
1) x²-9=0 means : x²-3² = (x-3)(x+3) = 0 .... use identity : a²-b² = (a-b(a+b)
use the Zero Product Property; x-3=0 or x+3=0 so : x=3 or x= +3
2) x²+4x = 0....using factoring : x(x+4)=0 means : x=0 or x+4=0
x=0 or x= - 4
3d+5+d-2
The answer would be 4d-3
2 doesn't work, because that would give you 7/0 on the left.... therefore C and D are out. 4 works, giving .5=.5, so you don't have to test -5 since 4 and -5 is not an option.
