x^{2} - 64 = 63

x = - 127 or x = - 1 or x = 1 or x = 127

Decimal Notation

x = - 11.26942 \dots, x = - 1, x = 1, x = 11.26942 \dots

Solution steps

x^{2} - 64 = 63

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} - 64 = - 63 or x^{2} - 64 = 63

x^{2} - 64 = - 63 or x^{2} - 64 = 63

(x = - 1 or x = 1) or (x = - 127 or x = 127)

x = - 127 or x = - 1 or x = 1 or x = 127

4 + x + 2 - 2 x = 5

x^{2} - 4 x + 8 = 0

x^{2} + x + 4 = 0

\frac{10}{3} x - x^{2} - 1 = 0
