6(2a plus b)
If I've read your question correctly, you need to subtract: a2 +2a -7 a2 -4a2 +5a2 -6 = 2a2 -6 Note, if x - y = z, then y = x - z; so: 2a2 -6 - (a2 -2a +1) = 2a2 -6 - a2 +2a -1 = a2 +2a -7
2a + a = 3a
2(a + 7)(a - 6)
(6ab + 9b)/(2a + 3) = 3b(2a + 3)/(2a + 3) = 3b
The value of a in the equation 5a plus 2a = 6-6a is a=6/11.
6+7a+6b
a = 1
5a + 11
6(2a plus b)
a + a + a - 2a = 3a - 2a = a
(a + 3)( b + 2)
6
7
= a + b - 2
