7 y^{2} - 9 y^{2} = 63

y = \frac{3 7}{2} i, y = - \frac{3 7}{2} i

Solution steps

7 y^{2} - 9 y^{2} = 63

Add similar elements:

7 y^{2} - 9 y^{2} = - 2 y^{2}

- 2 y^{2} = 63

Divide both sides by

- 2

y^{2} = - \frac{63}{2}

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

y = - \frac{63}{2}, y = - - \frac{63}{2}

- \frac{63}{2} = \frac{3 7}{2} i

- - \frac{63}{2} = - \frac{3 7}{2} i

y = \frac{3 7}{2} i, y = - \frac{3 7}{2} i

x^{2} + 1 = 4

- (- 5) y + (- 5) = - 5 y^{2} - 5

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

2 k^{2} + 7 k + 6 = 0

x^{2} + 16 x + 46 = 0
