x(x+7)=295

Solution for x(x+7)=295 equation:

x(x+7)=295

We move all terms to the left:

x(x+7)-(295)=0

We multiply parentheses

x^2+7x-295=0

a = 1; b = 7; c = -295;
Δ = b2-4ac
Δ = 72-4·1·(-295)
Δ = 1229
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(7)-\sqrt{1229}}{2*1}=\frac{-7-\sqrt{1229}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+\sqrt{1229}}{2*1}=\frac{-7+\sqrt{1229}}{2}
