Answer 1

Answer:

first of all write the given equation :

3(2a-b)² - 19(2a-b) +28

Step-by-step explanation:

= 3( we will use the formula i.e., (a-b)²=a²-2ab+b²)

=3[2a²-2×2a+(-b²) ] - 19(2a-b) +28

= 3[ 4a-4a+b] - 19(2a-b)+28

= 3[ (+) (-) will be canceled now only b is left here ...] -19(2a-b) +28

= 3b-19(2a-b) +28

= 3b ( now we will multiply here )+ 28

= 3b - 38a - 19b +28

= now , if we solve the above equation we will get ;

= -16b -38a+28

now, we will have to split the middle term.

= we will multiply the first term with the last term. after multiplying we get ; 448 so now take the L.C.M of 448

it will be -

= -16b - 38a +28

= -16b - 28a -10a +28

= now we will take the common;

= -4(4b-7a) -2(5a-14)

after solving it ,we get ;

= (2a-b-4) (6a-3b -7)
