Solve for the variable k.<br> m<br> __ = x<br> k
Tresset [83]
M/k=x
(m)m/k=x(m)
k=xm

Because you are diving one the side where m/k, you need to multiply m to both sides to get rid of it on one. Therefore, you are left with K=XM

tigry1 [53]

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.
