Question

Решите уравнение...  6x^2-28x=-32

Answer 1

6x^2-28x+32=0 D=(-28)^2-4*6*32=16 x1=(28-4)/2*6=2 x2=(28+4)/2*6=2 целых 2/3.

Answer 2

6$x^{2}$-28x=-32

6 $x^{2}$-28x+32=0

Д=784-4*6*32=784-768=16

$x_{1}$=$= frac{28-4}{6*2} = frac{24}{12} =2$

$x_{2} = frac{28+4}{6*2} = frac{32}{12}=2 frac{8}{12}=2 frac{2}{3}$
