Answer:
35=31
Step-by-step explanation:
[10x2+(30-15)]=7+3x8
[10x2+15]=7+24
[20+15]=31
35=31
Multiply the first coefficient (3) and the last term (2) to get 3*2 = 6
We need to find two numbers that
a) multiply to 6
AND
b) add to -5 (middle coefficient)
Such two numbers are -3 and -2
-3 times -2 = 6
-3 plus -2 = -5
So we can break up the -5x into -3x-2x and then factor by grouping
--------------
3x^2-5x+2
3x^2-3x-2x+2
(3x^2-3x)+(-2x+2)
3x(x-1)+(-2x+2)
3x(x-1)-2(x-1)
(3x-2)(x-1)
So the two factors are (3x-2) and (x-1)
The answers are A and C
