Question

(2а + b)^2 - ба - 3b - 4 ANSWER=(2a+b-4)(2a+b+1) solve it fast please​

Answer 1

Answer:

solution = (2a+b+1) (2a+b-4)

Answer 2

(2a +b)² -3(2a+b) -4

Now we split the middle term

(2a+b)² -4(2a+b) + (2a+b) -4

_____________|________

separating into two parts and taking common in first part as (2a+b) and 1 in the second part

(2a+b){(2a+b)-4} +1{(2a+b)-4}

(2a+b)(2a+b-4) + 1(2a+b-4)

(2a+b+1) (2a+b-4)
