dolphi86 [110]

Answer:

Step-by-step explanation:

Given that the number of males in the classroom is three more than twice the number of females.

Let x be the no of males then no of females = 57-x

Also we have 3 more than twice no of females as

2(57-x)+3

This equals x

2(57-x)+3=x\\114-2x+3=x\\3x=117\\x=39

No of males = 39, no of females = 18

= (6x-7)(x-2)

6x^2-19x + 14 = (6x-7)(x-2)
