Verified answer

use the foil method

f = first

o = outside

i = inside

l = last

first multiply the first numbers of each equation (3x)(2x)=6x^2

now multiply the outside numbers (3x)(5)=15x

now the inside numbers (-1)(2x)=-2x

finally the last numbers (-1)(5)=-5

no put in proper order 6x^2 + 15x -2x - 5=

=6x^2 + 13x -5

so C would be the proper answer

= (3x - 1)(2x + 5)

= 6x² + 15x - 2x - 5

= 6x² + 13x - 5

Answer: C) 6x² + 13x - 5

(3x-1)(2x+5)

first times 3x by 2x to get 6x^2, times 3x by 5 to get 15x

then times -1 by 2x to get -2x, and -1 by 5 to get -5

6x^2+15x-2x-5=6x^2+13x-5 which is C

Using the FOIL method, we multiply:

(F)irst terms

(O)utside terms

(I)nside terms

(L)ast terms

We take 3x*2x and get:

*6x^2*

then...

3x*5 and get

*15x*

And then...

-1*2x and get

*-2x*

then...

-1*5 and get

*-5*

... Combine all the terms I just calculated, and you get

6x^2+13x-5...C

C
