Question

Factor the following polynomials completely. (10 pts)

x2-16_______________________________
x2-81_______________________________
x3-1000 ____________________________
a2+4a+4____________________________
x2+144 ____________________________
answer plss

Answer 1

Answer:

1.x^2-16=0

x^2=16

x=4

2.x^2-81=0

x^2 =81

x=9

3.x^3-1000=0

x^3=1000

x=(1000)^1/3

4.a^2+4a+4=0

a=-2 and a=-2(by factorising)

5.x^2+144=0

x^2=-144

x=-12

so first answer => x=4

second answer=>x=9

third answer=>x=(1000)^1/3

forth answer=>a=-2 and a=-2

fifth answer=>x=-12

hope it helps
