Answer:
x² + 2x + 1 = 2x + 2
Step-by-step explanation:
Multiply without the multiplication symbol so use distributive property.
(x+1)(x+1) = 2(x+1)
Use the FOIL method (first, outer, inner, last)
(x)(x)+(x)(1)+(1)(x)+(1)(1) = (2)(x)+(1)(2)
which will give you:
x²+x+x+1 = 2x+2
combine like terms
x²+2x+1 = 2x+2
ta da! hope this helps
