complete the square

9 x^{2} - 6 x

9 (x - \frac{1}{3})^{2} - 1

Solution steps

9 x^{2} - 6 x

Write

9 x^{2} - 6 x

in the form:

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

Factor out

9

9 (x^{2} - \frac{2 x}{3})

2 a = - \frac{2}{3} : a = - \frac{1}{3}

Add and subtract

(- \frac{1}{3})^{2}

9 (x^{2} - \frac{2 x}{3} + (- \frac{1}{3})^{2} - (- \frac{1}{3})^{2})

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

x^{2} - \frac{2}{3} x + (- \frac{1}{3})^{2} = (x - \frac{1}{3})^{2}

9 ((x - \frac{1}{3})^{2} - (- \frac{1}{3})^{2})

Simplify

9 (x - \frac{1}{3})^{2} - 1

3 y (y) = x^{2} + 12

(4 x - 3)^{2} + (4 x + 3)^{2} = 25

4 x^{2} + 3 x = c

100 - 4 x = 0.6 x^{2} - 12 x + 80

75 = 3 w^{2}
