Question

Write a quadratic equation with roots of 13 and -72.

1) y = (x - 3)(7x²)
2) y = (x³)(7x - 2)
3) y = (3x - 1)(2x + 7)
4) y = (3x + 1)(2x - 7)

Answer 1

The quadratic equation with roots of 13 and -72 can be written as y = (x - 13)(x + 72).

Step-by-step explanation:

The quadratic equation with roots of 13 and -72 can be written as:

y = (x - 13)(x + 72)

This equation represents a parabola that will intersect the x-axis at 13 and -72. The factors (x - 13) and (x + 72) are the expressions representing the differences between x and the roots.
