Solve 2(2x-1) -6(1-2x) 2x=2(5x-5)

Question

Solve the equation(The real numbers system)

x \in / R

Alternative Form

No real solution

Evaluate

2 (2 x - 1) - 6 (1 - 2 x) \times 2 x = 2 (5 x - 5)

Multiply

More Steps

2 (2 x - 1) - 12 x (1 - 2 x) = 2 (5 x - 5)

Expand the expression

More Steps

- 8 x - 2 + 24 x^{2} = 2 (5 x - 5)

Expand the expression

More Steps

- 8 x - 2 + 24 x^{2} = 10 x - 10

Move the expression to the left side

- 18 x + 8 + 24 x^{2} = 0

Rewrite in standard form

24 x^{2} - 18 x + 8 = 0

Substitute a= 24,b= - 18 and c= 8 into the quadratic formula x = \frac{- b \pm b ^{2} - 4 a c}{2 a}

x = \frac{18 \pm ( - 18 ) ^{2} - 4 \times 24 \times 8}{2 \times 24}

Simplify the expression

x = \frac{18 \pm ( - 18 ) ^{2} - 4 \times 24 \times 8}{48}

Simplify the expression

More Steps

x = \frac{18 \pm - 444}{48}

Solution

x \in / R

Alternative Form
