5p-(15p*15p)=0

Solution for 5p-(15p*15p)=0 equation:

5p-(15p*15p)=0

We add all the numbers together, and all the variables

5p-(+15p*15p)=0

We get rid of parentheses

5p-15p*15p=0

Wy multiply elements

-225p^2+5p=0

a = -225; b = 5; c = 0;
Δ = b2-4ac
Δ = 52-4·(-225)·0
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-5}{2*-225}=\frac{-10}{-450}
=1/45
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+5}{2*-225}=\frac{0}{-450}
=0
