a^{2} + 2 a - 3 = 0

a = 1, a = - 3

Solution steps

a^{2} + 2 a - 3 = 0

Move

3

to the right side

a^{2} + 2 a = 3

Rewrite in the form

(x + b)^{2} = b

(a + 1)^{2} = 4

For

the solutions are

f (x) = a, - a

Solve

a + 1 = 4 : a = 1

Solve

a + 1 = - 4 : a = - 3

The solutions to the quadratic equation are:

a = 1, a = - 3

x, g = x^{2} + y^{2} + z^{2}

x^{2} + 18 x + 67 = 0

(x - 7)^{2} = 7

1.2 x^{2} + 5 x = 3

(8 - d)^{2} + 81 = 100
