When 3a2-2a plus 5 subtracted by a2 plus a equals 1?

Answer 1

Not sure why it is 3a2- if you mean 3*a*2, then:

3*a*2=6a

(6a-2a)+5-2(a (or a2)+a)=1

4a+5-(2a+a)=1

4a+5-2a-a=1

Then take the 5 over (remember, the +5 become -5 when transposed):

4a-2a-a=1-5

Solving the equations on both sides gives:

a=-4

Is this your answer?
