if (ax + 3)(bx + 5) - 35x? kx + 15 for all values of x, and a + b = 12, what are the two possible values for k?

=634

Solution by separating parts

Rewriting our equation with parts separated

=6+38+38

Solving the fraction parts

38+38=68

Reducing the fraction part, 6/8,

68=34

Combining the whole and fraction parts

6+34=634
