Solution equation: (30-2x) (22-2x) = 165

Solution equation: (30-2x) (22-2x) = 165


660-60x-44x+4x²=165
4x²-104x+495=0
4x²-104x+675=180
（2x-26）²=180
（x-13）²=45
x-13=±3√5
x=13±3√5



Solve the equation (30-2x) (20-2x) = 200


（30-2x)(20-2x)=200
It unfolds well
600-100x+4x^2=200
4x^2-100x+400=0
x^2-25x+100=0
(x-20)(x-5)=0
x=25,x=5



2X + 30% x = 14.95


2x＋30%x=14.95
2.3x=14.95
x=14.95÷2.3
x=6.5



How to solve 2x * (x + 2x / 3) = 480


2x*x*(1+2/3)=480
x*x=144
x=+-12
