Solve x^2-5x-7=2m

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

5^{2} + 28 + 8 m

Evaluate the power

25 + 28 + 8 m

Add the numbers

53 + 8 m

x = \frac{5 \pm 53 + 8 m}{2}

Solution

x = \frac{5 + 53 + 8 m}{2} x = \frac{5 - 53 + 8 m}{2}
