Question

Please help i have no idea how to do this problem
can you show steps and explain if possible
x^2-1.4x+.49 factor completely

Answer 1

start by multiplying all terms by 100 to get rid of the decimal...it will make the job A LLOT easier

100x^2 - 140x + 49

now can you factor it out? or do you need more help?

Answer 2

no I can get it from here thank you so much

Answer 3

That works, but you'll have to remove that 100 after you factor it.
I don't know the nitty gritty work in factoring, but here's one way you can go about it:

x^2 - 1.4x + 0.49
This is equal to
x^2 - 0.7x - 0.7x + 0.49
x(x - 0.7) - 0.7(x - 0.7)

And from there, it should be simple.
