Which shows the correct substitution of the values a, b, and c from the equation 1 = –2x + 3x2 + 1 into the quadratic formula? Q
Tanzania [10]

First of all, you have to manipulate the equation into the standard

ax^2+bx+c=0

form. You can simplify the 1's on both sides and you have

3x^2-2x=0

This means that your coefficients are

a=3,\quad b=-2,\quad c=0

And since the solving formula is

x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

Plugging your values yields

x_{1,2}=\dfrac{-(-2)\pm\sqrt{(-2)^2-4\cdot 3\cdot 0}}{2\cdot 3}
