Question

Using complete sentences, explain how to factor each one.  10x^2 − 7x − 3 using the ax^2+bx+c method.

anonymous · Answer

divide thro' by 10 to get     x^2 -(7/10)x-3/10=0
put x terms on left        numbers on right
1/2 co-eff of x term and square it(7/20)^2    and add it to both sides
the left side will be a perfect square (x-7/20)^2
square root both sides and simplify
(x-7/20)  =3/10 +(49/400)
x =1 or (-3/10)

This is algebra. I have to make the equation.  I am factoring trinomials.

anonymous · Answer

No solving for x.

anonymous · Answer

you have been asked to factor

anonymous · Answer

this can factor without all this (x-1)(10x+3) same answer

anonymous · Answer

but you are asked to use sentences

Oh ok I got it! Thanks. I was just having a problem with the ending result!
