$x=\frac{-10\pm \sqrt{10^2-4\cdot 25}}{2}$
Learn how to solve equations quadratiques problems step by step online. Solve the quadratic equation x^2+10x+25=0. Apply the formula: x^2+bx+c=0\to x=\frac{-b\pm \sqrt{b^2-4c}}{2}, where b=10, c=25, bx=10x, x^2+bx=x^2+10x+25 and x^2+bx=0=x^2+10x+25=0. Apply the formula: a=b\to a=b, where a=x and b=\frac{-10\pm \sqrt{10^2-4\cdot 25}}{2}. Apply the formula: x=\frac{b\pm c}{f}\to x=\frac{b+c}{f},\:x=\frac{b-c}{f}, where b=-10, c=0 and f=2. Apply the formula: a+b=a+b, where a=0, b=-10 and a+b=-10+0.
