Question

3.
Solve for x: 2(x + 1) + } (x - 1) = x (x - 2)​

Answer 1

Answer:

x= 5 /2 + /−1 /2 √29

Step-by-step explanation:

Let's solve your equation step-by-step.

2(x+1)+x−1=x(x−2)

Step 1: Simplify both sides of the equation.

3x+1=x2−2x

Step 2: Subtract x^2-2x from both sides.

3x+1−(x2−2x)=x2−2x−(x2−2x)

−x2+5x+1=0

For this equation: a=-1, b=5, c=1

−1x2+5x+1=0

Step 3: Use quadratic formula with a=-1, b=5, c=1.

x=$x=\frac{5}{2}+/-\frac{1}{2}\sqrt{29}$
