Which shows the correct substitution of values a, b, and c from the equation 1=-2x+3x^2+1 is the quadratic formula ?

Step-by-step explanation:

* Lets revise the general form of the quadratic equation

- The general form of the quadratic equation is Ax² + Bx + C = 0,

  where A , B , C are constant

# A is the coefficient of x²

# B is the coefficient of x

# C is the numerical term

- The quadratic formula is

* Lets solve the problem

∵ 1 = -2x + 3x² + 1

- Subtract 1 from both side

∴ 0 = -2x + 3x²

- Switch the two sides

∴ -2x + 3x² = 0

- Arrange the equation from the greatest power of x to the smallest

∴ 3x² - 2x = 0

∵ A is the coefficient of x²

∴ A = 3

∵ B is the coefficient of x

∴ B = -2

∵ C is the numerical term

∵ There is no numerical term

∴ C = 0

- Substitute the values of A , B , C in the formula

∴

25/14 or 1.
