-13p^2=-30p

Solution for -13p^2=-30p equation:

-13p^2=-30p

We move all terms to the left:

-13p^2-(-30p)=0

We get rid of parentheses

-13p^2+30p=0

a = -13; b = 30; c = 0;
Δ = b2-4ac
Δ = 302-4·(-13)·0
Δ = 900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{900}=30$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(30)-30}{2*-13}=\frac{-60}{-26}
=2+4/13
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(30)+30}{2*-13}=\frac{0}{-26}
=0
