Best ResponseYou've already chosen the best response.2I'll do the first one and save the other two. 8x^2+10x+3 is of the form ax^2 + bx + c a = 8 b = 10 c = 3 To get started, look for two numbers that multiply to a*c and add to b. Multiply to 8*3 = 24 and add to 10. 6 and 4 multiply to 24 and add to 10. "Bust" the b 8x^2+10x+3 8 x^2 + 6x + 4x + 3 = 2x* ( 4x + 3) + 1*(4x + 3) = (4x + 3) * ( 2x + 1)

Best ResponseYou've already chosen the best response.12a^211a+12 2 X 12=24 8 X 3=24 8+3=11 =2a^2+8a+3a+12 =(2a^2+8a)(3a+12) =2a(a+4)+3(a+4) =(a+4)(2a+3)

Best ResponseYou've already chosen the best response.2c) 2a^211a+12  I think there is a sign error but am not sure. Let me look.

Best ResponseYou've already chosen the best response.1Ohhh i think i figured it out... It's supposed to be 8 X 3 =24 and (8)+(3)=11

Best ResponseYou've already chosen the best response.22a^211a+12 2 X 12=24 The two numbers have to multiply to 24 and add to 11 They would be 8 and 3.

Best ResponseYou've already chosen the best response.1okay well for part B, i can't figure out anything else that equals to 18 and adds up to 3 6m^23m3 6 X 3 = 18

Best ResponseYou've already chosen the best response.2Before going to that problem, this current problem where =(a+4)(2a+3) appears is the answer needs correcting.

Best ResponseYou've already chosen the best response.1part c) =2a^28a3a+12 =(2a8a)(3a+12) =(2a(a4)+3(a4) =(a4)(2a3)

Best ResponseYou've already chosen the best response.1now how about for part b? are the numbers 6 and 3?

Best ResponseYou've already chosen the best response.2b) 6m^23m3 Multiply to 18 and add to 3

Best ResponseYou've already chosen the best response.2Oh, first divide through by 3 because that is a common factor. 6m^23m3 = 3*( 2m^2 m 1) Focus on this: ( 2m^2 m 1) What are two numbers that multiply to 2 and add to 1 ?

Best ResponseYou've already chosen the best response.2We will put back the initial 3 after factoring this: ( 2m^2 m 1) 2 m^2 2m + 1m  1 = 2m(m 1) + 1(m  1) = (m  1) (2m +1) The final answer: 6m^23m3 = 3*(m  1) (2m +1)
