So the equations are equal
Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
Answer:
r=7v−12
Step-by-step explanation:
Let's solve for r.
−8−2r=−7v−7v+16
Step 1: Add 8 to both sides.
−2r−8+8=−14v+16+8
−2r=−14v+24
Step 2: Divide both sides by -2.
−2r
−2
=
−14v+24
−2
r=7v−12
