|x^2+3x|=10

x^{2} + 3 x = 10

x = - 5 or x = 2

Solution steps

x^{2} + 3 x = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} + 3 x = - 10 or x^{2} + 3 x = 10

x^{2} + 3 x = - 10 or x^{2} + 3 x = 10

No Solution or (x = - 5 or x = 2)

x = - 5 or x = 2

- 11 w > - 11

21 a + 8 x y^{3} - 24 y^{2} - 7 a x y

(\frac{1}{2} x^{2} y^{3})^{4} (4 x^{5} y^{3})^{2}

5 y - \frac{3}{5} = \frac{4}{5}

x^{2} = 15 x - 56
