Answer:
n(x)=x+4m(x)=5x
n(x)=x+4m(x)=5x 2
n(x)=x+4m(x)=5x 2 +17x−12
Subtract x from both sides.
4mx=5x^{2}+17x-12-x
Combine 17x and -x to get 16x.
4mx=5x^{2}+16x-12
The equation is in standard form.
4xm=5x^{2}+16x-12
Divide both sides by 4x.
\frac{4xm}{4x}=\frac{5x^{2}+16x-12}{4x}
Dividing by 4x undoes the multiplication by 4x.
m=\frac{5x^{2}+16x-12}{4x}
Divide 5x^{2}+16x-12 by 4x.
m=\frac{5x}{4}+4-\frac{3}{x}
Step-by-step explanation:
x=\frac{2\left(-\sqrt{m^{2}-8m+31}+m-4\right)}{5}<br/>x=\frac{2\left(\sqrt{m^{2}-8m+31}+m-4\right)}{5}
