Note: Excel returns the solution x = 5. Excel finds the other solution if you start with an x-value closer to x = -1. For example, enter the value 0 into cell A2 and repeat steps 5 to 9. To find the roots, set y = 0 and solve the quadratic equation 3x2 - 12x + 9.5 = 0.

A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand. To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.
