5 x^{2} - 72 = 4 x^{2}

x = 62, x = - 62

Decimal Notation

x = 8.48528 \dots, x = - 8.48528 \dots

Solution steps

5 x^{2} - 72 = 4 x^{2}

Move

72

to the right side

5 x^{2} = 4 x^{2} + 72

Move

4 x^{2}

to the left side

x^{2} = 72

For

x^{2} = f (a)

the solutions are

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

x = 72, x = - 72

72 = 62

- 72 = - 62

x = 62, x = - 62

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

3 x^{2} - 3 = 8 x

(3 x + 4)^{2} - 6 (3 x + 4) + 9 = 0

1 + 8 x - 0.6 x^{2} = 1 + 4 x - 0.2 x^{2}

y^{2} = 6 - 0
