Answer» Answer: Sure are you GOING to mark me as brainliest if helpful. Step-by-step explanation: = − ± 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. 2 − + 5 7 6 = 0 b^{2}-b+576=0 b2−b+576=0 = 1 a={\color{#c92786}{1}} a=1 = − 1 b={\color{#e8710a}{-1}} b=−1 = 5 7 6 c={\color{#129eaf}{576}} c=576 = - ( − 1 ) ± ( − 1 ) 2 − 4 ⋅ 1 ⋅ 5 7 6 √ 2 ⋅ 1 b=\frac{-({\color{#e8710a}{-1}}) \pm \sqrt{({\color{#e8710a}{-1}})^{2}-4 \CDOT {\color{#c92786}{1}} \cdot {\color{#129eaf}{576}}}}{2 \cdot {\color{#c92786}{1}}} b=2⋅1−(−1)±(−1)2−4⋅1⋅576 |
