Answer:
-2a - 2b
Step-by-step explanation:
Question : (4a + b)-3(2a + b)
= 4a + b - 6a - 3b
= 4a - 6a + b - 3b
= -2a + (-2b)
= -2a -2b
If you need detail solution here ;
first + multiply both 4a and b
first -3 multiply both 2a and b and then -3×2a= -6a
-3×b = -3b
and it will be 4a + b -6a -3b,then collect like terms
4a - 6a + b -3b
= -2a +(-2b) in this part + tims - = -
= -2a - 2b
