    Answer: a= \frac{-bx-c+y}{x^{2} }

    Step-by-step explanation: Step 1: Flip the equation.

    ax²+bx+c=y

    Step 2: Add -bx to both sides.

    ax²+bx+c+−bx=y+−bx

    ax²+c=−bx+y

    Step 3: Add -c to both sides.

    ax²+c+−c=−bx+y+−c

    ax²=−bx−c+y

    Step 4: Divide both sides by x^2.

    \frac{ax^{2} }{x^{2} } = \frac{-bx-c+y}{x^{2} }
