Step-by-step explanation:
Let's simplify step-by-step.
x2−1−3(2x−2)(x−2)
Distribute:
=x2+−1+−6x2+18x+−12
Combine Like Terms:
=x2+−1+−6x2+18x+−12
=(x2+−6x2)+(18x)+(−1+−12)
=−5x2+18x+−13
Answer:
=−5x2+18x−13
Answer:
x=7/5
Step-by-step explanation:
Step-by-step explanation:
First, multiply each side of the equation by
2
to eliminate the fraction while keeping the equation balanced:
2×A=2×h2(a+b)
2A=2×h2(a+b)
2A=h(a+b)
Now, divide each side of the equation by
a
+
b
to solve for
h
while keeping the equation balanced:
2Aa+b=h(a+b)a+b
2Aa+b=h(a+b)a+b
2Aa+b=h
h=2Aa+b
