6p^2+42p+36=0

Solution for 6p^2+42p+36=0 equation:

6p^2+42p+36=0

a = 6; b = 42; c = +36;
Δ = b2-4ac
Δ = 422-4·6·36
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{-(42)-30}{2*6}=\frac{-72}{12}
=-6
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(42)+30}{2*6}=\frac{-12}{12}
=-1
