Answer:
(X+2)(v-5)
Step-by-step explanation:
first, group and factor out the greatest common factor and combine to get (x+2)(v-5)
Answers: b, d and e
b.The graph has a relative minimum
d. The graph has an x intercept at 3,0
e. the graph has an y intercept at 0,-15
f(x)=(x+5)(x-3)
The given equation is in the form of f(x) = a(x-b)(x-c)
If 'a' is positive then graph has a relative minimum
If 'a' is negative then graph has a relative maximum
Here a=1 that is positive so graph has a relative minimum .
To find x intercept we set f(x) =0 and solve for x
0=(x+5)(x-3)
x+5 =0 -> x = -5 so x intercept is (-5,0)
x - 3=0 -> x= 3 so x intercept is (3,0)
To find y intercept we plug in 0 for x
y=(x+5)(x-3)
y=(0+5)(0-3) = -15
so y intercept is (0,-15)
(x+3y)^2
((-5)+3(-6))^2
(-5+3·6)^2
(-5+18)^2
(-5+18)(-5+18)
25-90-90+324
169 is your answer.
Your set the equation equal to 0 and you start factoring it, if it doesn’t factor out then you use the quadratic formula but if you do that then set it equal to “X”, not equal to 0
