Решите уравнения: 1)(2y-1)(2)=10-4Y 2)(3m-2)(3m+2)=5m(2) 3)1,44-x(2)=3x(2) (2) - это во...

$(2y-1)^2=10-4y;\\ 4y^2-4y+1=10-4y;\\ 4y^2+1=10;\\ 4y^2=10-1;\\ 4y^2=9;\\ y^2=\frac{9}{4};\\ y_1=1.5; y_2=-1.5$

$(3m-2)(3m+2)=5m^2;\\ 9m^2-4=5m^2;\\ 9m^2-5m^2=4;\\ 4m^2=4;\\ m^2=\frac{4}{4};\\ m^2=1;\\ m_1=-1; m_2=1$

$1.44-x^2=3x^2;\\ 3x^2+x^2=1.44;\\ 4x^2=1.44;\\ x^2=\frac{1.44}{4};\\ x^2=0.36;\\ x_1=-0.6; x_2=0.6$
