complete the square

w^{2} - 18 w

(w - 9)^{2} - 81

Solution steps

w^{2} - 18 w

Write

w^{2} - 18 w

in the form:

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

2 a = - 18 : a = - 9

Add and subtract

(- 9)^{2}

w^{2} - 18 w + (- 9)^{2} - (- 9)^{2}

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

w^{2} - 18 w + (- 9)^{2} = (w - 9)^{2}

(w - 9)^{2} - (- 9)^{2}

Simplify

(w - 9)^{2} - 81

(x - (3 + 7)) (x - (3 - 7)) = 0

- 39.662 x^{2} + 548.12 x - 564.5 = 548.12

2 x^{2} = 3 x + 54

1 - 1.9 x - 0.1 x^{2} = 0

u, E = \frac{1}{2} m v^{2} - \frac{1}{2} m u^{2}
