In the right triangle shown, m\angle D = 60\degreem∠D=60°m, angle, D, equals, 60, degree and EF= 4\sqrt{3}EF=4 3 E, F, equals, 4, square root of, 3, end square root. How long is DEDED, E? Choose 1

Step-by-step explanation:

x-intercepts exist when y = 0.  Set the quadratic equal to 0 and solve each expression for x:

0 = (x - 2)(x + 5)

By the Zero Product Property, either x - 2 = 0 or x + 5 = 0 (because when you multiply 0 by anything, you get a 0. Which means that one of these expressions has to equal 0.)

x - 2 = 0 so

x = 2

x + 5 = 0 so

x = -5

Again, the x-intercept exists when y = 0, so the number for y in the coordinates will be 0's. (2, 0) and (-5, 0) are your coordinates.
