Question

What are the solutions of 4x2 − 4x − 3 = 0?

Answer 1

you can factor it out..break down the middle term

\[4x^2 +2x - 6x - 3 = 0\]
group
\[(4x^2 + 2x) - (6x + 3) = 0\]
factor out
\[2x(2x + 1) - 3(2x+1) = 0\]
factor again
\[(2x+1)(2x-3) = 0\]
can you find the solutions now?

Answer 2

Nice work with the ac method.
