Math Problem Statement

when y=0, 2(x-1)^2+3=0

Solution

To solve the equation 2(x1)2+3=02(x-1)^2 + 3 = 0 for xx when y=0y = 0, follow these steps:

  1. Set the equation equal to zero: 2(x1)2+3=02(x-1)^2 + 3 = 0

  2. Isolate the quadratic term: 2(x1)2=32(x-1)^2 = -3

  3. Divide both sides by 2: (x1)2=32(x-1)^2 = -\frac{3}{2}

  4. Take the square root of both sides: x1=±32x-1 = \pm \sqrt{-\frac{3}{2}}

    Recall that 1=i\sqrt{-1} = i, where ii is the imaginary unit.

  5. Simplify the right-hand side: x1=±i32x - 1 = \pm i\sqrt{\frac{3}{2}}

  6. Solve for xx: x=1±i32x = 1 \pm i\sqrt{\frac{3}{2}}

So, the solutions are: x=1+i32andx=1i32x = 1 + i\sqrt{\frac{3}{2}} \quad \text{and} \quad x = 1 - i\sqrt{\frac{3}{2}}

These are complex roots, meaning there are no real values of xx that satisfy the equation.
