(p-8)(p-3)=

Solution for (p-8)(p-3)= equation:

(p-8)(p-3)=

We move all terms to the left:

(p-8)(p-3)-()=0

We add all the numbers together, and all the variables

(p-8)(p-3)=0

We multiply parentheses ..

(+p^2-3p-8p+24)=0

We get rid of parentheses

p^2-3p-8p+24=0

We add all the numbers together, and all the variables

p^2-11p+24=0

a = 1; b = -11; c = +24;
Δ = b2-4ac
Δ = -112-4·1·24
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{-(-11)-5}{2*1}=\frac{6}{2}
=3
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+5}{2*1}=\frac{16}{2}
=8
