Question

(3^3 ; 4^3) × (-3^3 /4^3) =(-3^6/4^6) this statement is true or false
​

Answer 1

Step-by-step explanation:

Use the quadratic formula

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.
