x^{2} + 6 x - 40 = 0

x = 4, x = - 10

Solution steps

x^{2} + 6 x - 40 = 0

Move

40

to the right side

x^{2} + 6 x = 40

Rewrite in the form

(x + a)^{2} = b

(x + 3)^{2} = 49

For

the solutions are

f (x) = a, - a

Solve

x + 3 = 49 : x = 4

Solve

x + 3 = - 49 : x = - 10

The solutions to the quadratic equation are:

x = 4, x = - 10

y, \frac{x ^{2}}{81} + \frac{y ^{2}}{144} = 1

45 x^{2} - 3 x = 2 x

x^{2} + 1 2^{2} = 2 0^{2}

- 2 x + 4 x^{2} + 17 = - 5 x

x, f = x^{2} y + 2 x + 3 y
