Question

find the roots x^2+3x=0​

Answer 1

Answer:

x^2 +3x = 0

lets find the answer

Step-by-step explanation:

x^2 = -3x

x = $\sqrt{-3x}$

Answer 2

Answer:

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.
