How do you solve y equals x2-3x-20 using systems?

Answer 1

To solve the equation y = x^2 - 3x - 20 using systems, you can set up a system of equations by substituting y with x^2 - 3x - 20. This gives you the equation x^2 - 3x - 20 = 0. You can then solve this quadratic equation using factoring, the quadratic formula, or completing the square to find the values of x. Once you have the values of x, you can substitute them back into the original equation to find the corresponding values of y.

Answer 2

y = x2 - 3x - 20 is a formula linking two variables, x and y. It does not - indeed, it cannot - have a solution.

The equation x2 - 3x - 20 = 0 has solutions at x = -3.217 and x = 6.217 approx.
