2x²-2x-12=0
simplify it into x²-x-6=0
factored form: (x-3)(x+2)=0
solutions: x-3=0 or x+2=0
x=3 or x=-2
Not sure how to explain "what the solutions mean for the equation". One thing you can say is that the solutions mean the equations have two roots/two zeros: 3 and -2, or the graph of 2x²-2x-12 intersects the x axis at (3,0) and (-2,0).

Given the quadratic function f(x) = (x + 6)(x – 3):

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

Given quadratic function is,

f(x) = (x + 6)(x - 3)

For x-intercept,

Substitute the value f(x) = 0.

(x + 6)(x - 3 = 0

x = 3, -6

So the x-intercepts will be,

(-6, 0) and (3, 0)

For y-intercept,

Substitute the value for x = 0,

f(0) = (0 + 6)(0 - 3)

= -18

Therefore, y-intercept of the given quadratic function will be (0, -18).

Eighteen percent of apples grown in an orchard have defects. Let X = the number of apples that are randomly inspected from the o

KonstantinChe [14]

Answer:

0.219 or 21.028%

Step-by-step explanation:

0.18 are defective, so

P(x=1) = 0.18

P(x=2) = 0.18^2 = 0.0324

P(x=3) = 0.18^3 = 0.005832

P(x=4) = 0.18^4 = 0.00104976

Then add them together: 0.21928176
