complete the square

x^{2} - 15 x

(x - \frac{15}{2})^{2} - \frac{225}{4}

Solution steps

x^{2} - 15 x

Write

x^{2} - 15 x

in the form:

x^{2} + 2 a x + a^{2}

2 a = - 15 : a = - \frac{15}{2}

Add and subtract

(- \frac{15}{2})^{2}

x^{2} - 15 x + (- \frac{15}{2})^{2} - (- \frac{15}{2})^{2}

x^{2} + 2 a x + a^{2} = (x + a)^{2}

x^{2} - 15 x + (- \frac{15}{2})^{2} = (x - \frac{15}{2})^{2}

(x - \frac{15}{2})^{2} - (- \frac{15}{2})^{2}

Simplify

(x - \frac{15}{2})^{2} - \frac{225}{4}

v^{2} - 8 v + 45 = 0

x^{2} - 12 x = 10

5 x^{2} - 3 x + 5 = 0

3 x^{2} + x = 14

4 x^{2} + 8 x
