28 = 64 - 9 x^{2}

x = 2, x = - 2

Solution steps

28 = 64 - 9 x^{2}

Switch sides

64 - 9 x^{2} = 28

Move

64

to the right side

- 9 x^{2} = - 36

Divide both sides by

- 9

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

(- 4 + 2 i) (4 - 4 i)

354 + 33 - 2384

83 = 20 + 9 t

6 x^{2} + 13 x + 5 = 0

4 π^{2} \cdot (\frac{0.67}{( 1.675 ) ^{2}})
