complete the square

3 x^{2} - 6 x - 10

3 (x - 1)^{2} - 13

Solution steps

3 x^{2} - 6 x - 10

Write

3 x^{2} - 6 x - 10

in the form:

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

Factor out

3

3 (x^{2} - 2 x - \frac{10}{3})

2 a = - 2 : a = - 1

Add and subtract

(- 1)^{2}

3 (x^{2} - 2 x - \frac{10}{3} + (- 1)^{2} - (- 1)^{2})

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

x^{2} - 2 x + (- 1)^{2} = (x - 1)^{2}

3 ((x - 1)^{2} - \frac{10}{3} - (- 1)^{2})

Simplify

3 (x - 1)^{2} - 13

m^{2} = 5 m + 14

x^{2} + 2 x + 10 = - 2

- 9 x^{2} + 18 x + 35 = 0

7 x^{2} + 40 x = 12

(2 x - 5)^{2} - (x - 6)^{2} = 5
