a. \[(x+1)(2x+1) = x+2\] Remove the parenthesis: \[x+12x1 = x+2\] Combine like terms: \[x2x+11 = x+2\]

b. Similarly to part a: \[(4p^2−3q)−4(p^2−q)=7q\] Remove parenthesis: \[4p^2−3q−4p^2+4q=7q\] Combine like terms: \[4p^2−4p^2−3q+4q=7q\]

c. \[5k(k+1)−(k^2+5)=4k^2\] Multiply out: \[5k^2 + 5k−(k^2+5)=4k^2\] Remove parenthesis: \[5k^2 + 5k−k^25=4k^2\] Combine like terms: \[5k^2−k^2 + 5k5=4k^2\]

As you can see, none of these are actually equivalent. You have to change one of the sides (usually a plus or minus or a constant) to make them correct.
