9x^2=625
We move all terms to the left:
9x^2-(625)=0
a = 9; b = 0; c = -625;
Δ = b2-4ac
Δ = 02-4·9·(-625)
Δ = 22500
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{22500}=150$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-150}{2*9}=\frac{-150}{18} =-8+1/3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+150}{2*9}=\frac{150}{18} =8+1/3 $
