Please help me with this math question

Answer 1

The roots of the polynomial are the solutions to that equation.

If you consider the original equation,
`y=x^2-7x+10`, and the equation you're solving,
`x^2-7x+10=0`, the connection is that y=0.

In terms of the graph, you're looking where the graph crosses the line y=0, which is the x-axis.

In short, the solutions to that equation are the x-values where your graph crosses the x-axis: 2 and 5.

You can double check this by substituting in 2 and 5 (one at a time) to verify that they are solutions to the equation.
