-4x2+2x+2=0 what is ans​

Answer»

Answer:

Step-by-step EXPLANATION:

Use the quadratic formula

=

−

±

2

−

4

√

2

x=\frac{-{\COLOR{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{C}}}}{2{\color{#c92786}{a}}}

x=2a−b±b2−4ac​​

Once in standard form, IDENTIFY a, b and c from the original equation and PLUG them into the quadratic formula.
