Answer:
Step-by-step explanation:
This is more easily understood if you take out a common factor of -1
-1(x^2 + 15x + 56)
7*8 = 56
7 + 8 = 56
-1 (x +8)(x+7)
Answer:
No
Step-by-step explanation:
2y = 24
y = 24/2
y = 12
so the answer is incorrect
Answer:
x= 5/2 or 1/2
Step-by-step explanation:
absolute value always gives us positive
if |u| = 2, u can be -2 or 2
2x-3 = 2
2x = 5
x = 5/2
2x-3 = -2
2x = 1
x= 1/2
in general, set the stuff inside the absolute value to equal both positive and negative of the equivalent value
