x^{2} - 7 = 25

x = - 42 or x = 42

Decimal Notation

x = - 5.65685 \dots, x = 5.65685 \dots

Solution steps

x^{2} - 7 = 25

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} - 7 = - 25 or x^{2} - 7 = 25

x^{2} - 7 = - 25 or x^{2} - 7 = 25

No Solution or (x = - 42 or x = 42)

x = - 42 or x = 42

lo g_{3} (\frac{a}{3})

5 x^{2} + 42 x + 49

5 (x - 3) + 6 = 5 x - 10

9 (2 c + 7) = c^{2} + 17 c + 7

\frac{120 \cdot 60}{6}
