Question

Put the equation in the form ax2 + bx + c = 0. Enter exponents using the caret ( ^ ). For example, you would enter 4x2 as 4x^2. (2x+1)^2-x=6

Answer 1

Great, just expand the \((2x+1)^2\) using the formula for expanding binomial whole squares, that is: \((a+b)^2 = a^2 + b^2 + 2ab\).

then combine like terms, and simplify!
