Question

( -5x+3 ) ( -x+6 ) = 0

Answer 1

.........................

Answer 2

(-5x+3)(-x+6) = 0
5x^2 - 30x -3x + 18 = 0
5x^2 -33x + 18 = 0
D= (-33)^2 - 4*5*18=1089 - 360 = 729
x1,2= $\frac{-(-33) +-\sqrt{729}}{2*5}$ = $\frac{33+- 27}{10}$
x1=(33+27)/10= 60/10 = 6
x2=(33-27)/10= 6/10 = 0,6
Ответ: х1=6 , х2= 0,6
