    Step 1 ax2 + bx + c = 0 Step 2 ax2 + bx = − c Step 3 x2 + b over a times x equals negative c over a Step 4 x2 + b over a times x plus b squared over 4 times a squared equals negative c over a plus b squared over 4 times a squared Step 5 x2 + b over a times x plus b squared over 4 times a squared equals negative 4 multiplied by a multiplied by c, all over 4 multiplied by a squared plus b squared over 4 times a squared Step 6 the square of the quantity x plus b over 2 times a equals b squared minus 4 multiplied by a multiplied by c, all over 4 times a squared Step 7 x plus b over 2 times a equals plus or minus square root of the quantity b squared minus 4 times a times c over 4 times a squared equals plus or minus square root of b squared minus 4 times a times c, all divided by 4 times a Step 8 x = −negative b over 2 times a plus or minus square root of b squared minus 4 times a times c, all divided by 2 times a Step 9 x = negative b plus or minus square root of b squared minus 4 times a times c, all divided by 2 times a

    step 4 looks like this \[\left[\begin{matrix}x^2+b \\ x+b^2 \\ 4a^2 \end{matrix}\right] = \left[\begin{matrix}-c \\ a+b^2 \\ 4a^2 \end{matrix}\right]\]

    step 5 looks like \[\left[\begin{matrix}x^2+b \\ x+b^2 \\ 4a^2 \end{matrix}\right]=\left[\begin{matrix}-4ac \\ 4a^2+b^2 \\ 4a^2 \end{matrix}\right]\]
