Question

x(2x-3)=4x-3 дискриминант или не дискриминант

Answer 1

2x²-3x-4x+3=0

2x²-7x+3=0

D= 49-24= 25

x1= (7+5)/4= 3

x2= (7-5)/4= 1/2 ( или 0,5)

Answer 2

$2x^2-3x=4x-3\\2x^2-7x+3=0\\D=(-7)^2-4*2*3\\D=49-24=25\\x_{1} =\frac{7-5}{2*2} =\frac{2}{4}=0,5\\\\x_{2} = \frac{7+5}{2*2}=\frac{12}{4}=3$

Ответ: 0,5; 3
