Please help me out and explain it to me

A

Step-by-step explanation:

x^2-6x+25=0

A quadratic equation can be solved by using the quadratic formula,

So the equation to start with is ax^2+bx+c=0, thus your equation has the same layout.

a= 1

b= -6

c= 25

Then plug it in

When you have a negative in the root you have to take out an i

i = -

So when you take it out the negative isn't there anymore so you can simplify normally

Now split up the plus and minus

So the answer is A

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
