## Solve x^2+5x+7=0, Microsoft Math Solver

x^ {2}+5x+7=0. All equations of the form ax^ {2}+bx+c=0 can be solved using the quadratic formula: \frac {b±\sqrt {b^ {2}4ac}} {2a}. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction. x=\frac {5±\sqrt {5^ {2}4\times 7}} {2}

## Solve 5x^23x+7, Microsoft Math Solver

5 { x }^ { 2 } 3x+7. 5 x 2 3 x + 7. Quadratic equations such as this one can be solved by a new direct factoring method that does not require guess work. To use the direct factoring method, the equation must be in the form x^2+Bx+C=0.This is achieved by dividing both sides of the equation by 5.
