Factorize 1: x2-4x+4

2: x2-5x-6

3: x2-9x-10

4: x2-81

5: x2-361

x2-81=0

Step-by-step explanation:

where,

a2-b2=(a+b)

a2-b2= (a+b) (a-b)

so,

a=x

b=0

so the answer is 0

I hope it helps you

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
