Answer 1

6x(x-4)+2x(2-3x)=-25

<=> 6x²-24x+4x-6x²=-25

<=> -20x=-25

<=> x=\(\frac{5}{4}\)

Answer 2

6x(x - 4) + 2x(2 - 3x) = -25

6x² - 24 + 4x - 6x² = -25

4x - 24 = -25

4x = -25 + 24

4x = -1

x = -1 : 4 = -0,25

Answer 3

\(6x\left(x-4\right)+2x\left(2-3x\right)=-25\)

\(\Rightarrow6x^2-24x+4x-6x^2=-25\)

\(\Rightarrow\left(6x^2-6x^2\right)+\left(-24x+4x\right)=-25\)

\(\Rightarrow-20x=-25\)

\(\Rightarrow x=-25:-20\)

\(\Rightarrow x=\frac{5}{4}\)

Vậy  \(x=\frac{5}{4}\)
