F(x)=3^2-2and g(x) =4x+2 what is the value of (f+g)(2)
morpeh [17]

Step-by-step explanation:

f(x) =  {3}^{2}  - 2 = 9 - 2 = 7 \\ g(x) = 4x + 2 \\  \therefore \: (f + g)(x) = 7 + 4x + 2 \\  \therefore \: (f + g)(x) =  4x + 9 \\ \therefore \: (f + g)(2) =  4 \times 2 + 9 \\ \therefore \: (f + g)(2) =  8 + 9 \\  \red{\boxed{ \bold{ \therefore \: (f + g)(2) =  17}}}

How to use the zero product property and factoring solve for X
Marta_Voda [28]
Using the zero product property you can set each expression equal to 0 (or factor for some of them)
All you have to do is set them equal to zero and simplify to solve for x

a. (x+13)=0
x= -13
(x-7)=0
x=7

b. (2x+3)=0
x=-3/2
(3x-7)=0
x=7/3

c. x=0
(x-3)=0
x=3

d. x^{2} -5x=0
 needs to be factored 
factor out an x to get:
x(x-5) and set each equal to 0
x = 0       
(x-5)=0 
x=5

e. x^{2} -2x-35=0
 also needs to be factored
(x-7)(x+5)=0
(x-7)=0       (x+5)=0
x=7   x=-5

f. 3x^{2} +14x-5=0
Also needs to be factored using the ac method:
3 x^{2} +15x-x-5
3 x^{2} (x+5)-1(x+5)
(3x-1)(x+5)=0

(3x-1)=0
x=1/3
(x+5)=0
x=-5

I hope this helps! (if so, give brainliest please!!)

Which is a factor of: 2x^2+2x−12 ?
laiz [17]

Answer:

(x - 2) and (x + 3) is a factor of: 2x² + 2x - 12

Step-by-step explanation:

2x² + 2x - 12 given equation

Now divide it by 2 we get,

x² + x - 6

then

x² + x - 6

x² + 3x - 2x - 6

x(x + 3) - 2(x + 3)

<em><u>(x - 2) (x + 3)</u></em>
