(p+3)(p+10)=0

We multiply parentheses ..

(+p^2+10p+3p+30)=0

We get rid of parentheses

p^2+10p+3p+30=0

We add all the numbers together, and all the variables

p^2+13p+30=0

a = 1; b = 13; c = +30;

Δ = b^{2}-4ac

Δ = 13^{2}-4·1·30

Δ = 49

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{49}=7$$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(13)-7}{2*1}=\frac{-20}{2} =-10 $$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(13)+7}{2*1}=\frac{-6}{2} =-3 $
