7p^2-7p-(7p)=0

Solution for 7p^2-7p-(7p)=0 equation:

7p^2-7p-(7p)=0

We add all the numbers together, and all the variables

7p^2-14p=0

a = 7; b = -14; c = 0;
Δ = b2-4ac
Δ = -142-4·7·0
Δ = 196
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{196}=14$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-14)-14}{2*7}=\frac{0}{14}
=0
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-14)+14}{2*7}=\frac{28}{14}
=2
