Answer 1

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
