Which expression is a difference of squares with a factor of 2x + 5? 4x2 + 10 4x2 – 10 4x2 + 25 4x2 – 25
Answers
Answer:
The required expression is
Step-by-step explanation:
The difference of squares formula is given by
We have been given that one factor is 2x+5. Hence, a = 2x, b = 5
It means that other factor must be (a-b) = (2x-5)
Hence, in order to find the expression, we can multiply the factors.
Using the difference of squares formula
Therefore, the required expression is

for this question, you know what is x and you wanna find the y.
So the only thing you should do is to put 3 for x and solve the equation:
3 + y = 10
y = 10 -3
y = 7
Hava great one!
The problem already gave us x. So we plug it in.
3+y=10
We now want to make the variable by itself, so we subtract 3 to the other side.
y=10-3
Simple Math
y=7
I hope this helps;)

Step-by-step explanation:
x^2 - 8x + 15 = 0
Factor
What 2 numbers multiply to 15 and add to -8
-5*-3 = 15
-5-3 = -8
(x-5)(x-3) =0
Using the zero product property
x-5 =0 x-3 =0
x=5 x=3

Answer:
The value of k is -7
Step-by-step explanation:
We are given the graph of f(x) and g(x). If g(x)=f(x)+k
If we shift f(x) k unit vertical get g(x).
If k>0 then shift up
If k<0 then shift down.
f(x) and g(x) are both parabola curve.
First we find the vertex of f(x) and g(x)
Vertex of f(x) = (3,1)
Vertex of g(x) = (3,-6)
We can see change in y co-ordinate only.
f(x) shift 7 unit down to get g(x)
g(x)=f(x)-7
Therefore, The value of k is -7
moved from 1 to -6
movement up -7 units
k=-7
