а.
3m² - 11m = 0
m(3m - 11) = 0
m₁ = 0
3m - 11 = 0
m₂ = 11/3
б.
6p = - 7p²
7p² + 6p = 0
p(7p + 6) = 0
p₁ = 0
7p + 6 = 0
p₂ = -6/7
в.
-2(x + 5) = 7x² - 10
-2x - 10 = 7x² - 10
7x² + 2x = 0
x(7x + 2) = 0
x₁ = 0
7x + 2 = 0
x₂ = -2/7
г.
4(n² - 9) = 3(n - 12)
4n² - 36 = 3n - 36
4n² - 3n = 0
n(4n - 3) = 0
n₁ = 0
4n - 3 = 0
n₂ = 3/4
