Answer:
x = -7
x = 5
Step-by-step explanation:
The standard form of quadratic equations is
Ax^2 + Bx + C = 0
The factors need to multiply together to be C and add together to be B.
The two numbers that will multiply together to be -35 and add together to be 2 are -5 & 7.
The factor pairs are (x+7)(x-5). Zero product property means we set each of those factor pairs = 0 and solve.
x + 7 = 0
-7 -7 Subtract 7 from each side to solve
x = -7
x - 5 = 0
+5 +5 Add 5 to each side to solve
x = 5
Answer:
Step-by-step explanation:
First cross multiply:
2(x+2)=2x-2
Then Simplify:
2x+4=2x-2
Finally, Solve:
2x-2x=4+2
Ans: No Solution
Answer: C is not true
Step-by-step explanation:
I can't really explain why c is not true but I know for sure that A, B, and D are True.
