4p+7q
simply add the like terms: 4p -3p +2q -2q = p
3
17p+17q+p-7q-6p = 12p+17q
7q+13 = 52 7q = 52-13 7q = 39 q = 39/7
4p+7q
8 + 5p + 7q + 9 + 3p Reordering: 8 + 9 + 5p + 3p + 7q Combine like terms: 17 + 8p + 7q
14p + 14q + p - 7q - 6p = 9p + 7q
simply add the like terms: 4p -3p +2q -2q = p
3
17p+17q+p-7q-6p = 12p+17q
7q+13 = 52 7q = 52-13 7q = 39 q = 39/7
Let f(X)=2X2+6X+3 So f(-p)=f(2q) or 2p2-6p+3=8q2+12q+3 or p2-3p=4q2+6q or p2-4q2=3p+6q or (p+2q)(p-2q)=3(p+2q) so p-2q=3
-(b + c - p - 2q)(b + c + p + 2q)
5p-7q
3q + 5 + 2q + 5 = 65 5q + 10 = 65 5q = 55 q = 11 Check it. 33 + 5 + 22 + 5 = 65 It checks.
