Question

Решить уравнения...
Номера: 5.,6.

Answer 1

1) $frac{1}{6} x^{2} - frac{5}{6}=0$
    $frac{1}{6} x^{2} = frac{5}{6}$
    $x^{2} = frac{5}{6}: frac{1}{6}$
    $x^{2} = frac{5}{6}* frac{6}{1}$
    $x^{2} = frac{30}{6}$
    $x^{2} =5$
    x₁=-√5    x₂=√5

2) x²=7x
    x²-7x=0
    x(x-7)=0
    x₁=0    x-7=0
               x₂=7
