5(1-x)^2-6(x^2-3x-7)=x(x-3)-2x(x+5)-2

5 (1 - x)^{2} - 6 (x^{2} - 3 x - 7) = x (x - 3) - 2 x (x + 5) - 2

x = - \frac{7}{3}

Solution steps

5 (1 - x)^{2} - 6 (x^{2} - 3 x - 7) = x (x - 3) - 2 x (x + 5) - 2

Expand

5 (1 - x)^{2} - 6 (x^{2} - 3 x - 7) : - x^{2} + 8 x + 47

Expand

x (x - 3) - 2 x (x + 5) - 2 : - x^{2} - 13 x - 2

- x^{2} + 8 x + 47 = - x^{2} - 13 x - 2

Move

47

to the right side

- x^{2} + 8 x = - x^{2} - 13 x - 49

Subtract

- x^{2} - 13 x

from both sides

- x^{2} + 8 x - (- x^{2} - 13 x) = - x^{2} - 13 x - 49 - (- x^{2} - 13 x)

Simplify

21 x = - 49

Divide both sides by

21

x = - \frac{7}{3}

lo g_{2} (\frac{1}{8})

\frac{12 !}{4 ! 8 !}

\frac{\frac{1}{2 ( x + h )} - \frac{1}{2 x}}{h}

\frac{∣ x ∣}{2} > 3
