Question

Which of the following represents this function written in intercept form?
y= -x^2 - x +6

a. y= -(x+2)(x+6)
b. y= -(x-2)(x+3)
c. y= (-x+3)(x-4)
d. y= -(x+2)(x-6)

Answer 1

is b the right answer?

Answer 2

Are you trying to factor it? How do you write a quadratic equation in the form of intercept form?

Answer 3

y=a(x-r1)(x-r2)

Answer 4

-x^2 - x + 6 = -{ x^2 + x - 6 } = -{ x^2 + 3x - 2x - 6 } =
-{ x(x+3) - 2(x+3) } = -(x-2)(x+3)
