3+x(5-x)=(2-x)(x+3)
7-x(3+x)=(x+2)(5-x)
Помогите решить

3 + - x^2 + 5*x = (2-x)*(x+3)3 + - x^2 + 5*x = 6 - x - x^2-3 + 6*x = 06*x = 3x = 3 / (6)x = 1/2x1 = 0.57 - x^2 - 3*x = (x+2)*(5-x)7 - x^2 - 3*x = 10 - x^2 + 3*x-3 - 6*x = 0-6*x = 3x = 3 / (-6)x = -1/2x1 = -0.5

3+x(5-x)=(2-x)(x+3)3+5x-x^2=2x+6-x^2-3x2x=3x=1.57-x(3+x)=(x+2)(5-x)7-3x-x^2=5x-x^2+10-2x0x=3x=0
