Answer:
the positive x- intercept is x = + 9
Explanation:
the x- intercept is the point/s on the x- axis where the graph crosses it.
the y- coordinate of any point on the x- axis is 0
let y = 0 in the equation and solve for x , that is
y = (x + 2)(x - 9) ← substitute y = 0
(x + 2)(x - 9) = 0
equate each factor to zero and solve for x
x + 2 = 0 ( subtract 2 from both sides )
x = - 2
x - 9 = 0 ( add 9 to both sides )
x = 9
there are 2 x- intercepts at x = - 2 and x = 9
the value of the positive x- intercept is x = + 9
