Question

Factor the trinomial: 7x^2 + 41x - 6

Answer 1

7x^2+41x-6
=> 7x^2+42x-x-6

Answer 2

Now take 7x^2+42x. what is common in this equation ?

Answer 3

I get the idea of finding numbers for m and n and have factored it out to
7x(x+6) - (x-6). I think that is right?

Answer 4

yes u r right but u have done a mistake 7x(x+6)-1(x+6)

Answer 5

got it ?

Answer 6

7x^2 + 41x - 6
(x + 6)(7x - 1)

Answer 7

That is where I'm lost .....how did you you get (x+6)(7x-1)

Answer 8

do you know the foil method ?

Answer 9

7x(x+6)-1(x+6)
take (x+6) common

(x+6)(7x-1)

Answer 10

gt it ?

Answer 11

jitesmeghwal explains better then I do

Answer 12

Thanx buddy :)

Answer 13

Ok...the Foil method is first, outside, inside, last

Answer 14

only telling the truth :)

Answer 15

yes...first, outside, inside, last

Answer 16

Ok...(x+6)(7x-1) = 7x^2-x+42x-6 which in return is 7x^2+41x-6

Answer 17

a(b+c)=a(b)+a(c)=ab+ac

This is known as FOIL method :)

Answer 18

yes...that is how I do it
