Answer:
2x²y + 4x³
Step-by-step explanation:
2/7 x² ( 7y + 14x )
= (2/7 x² * 7y) + (2/7x² * 14x)
= 2x²y + 4x³
verification when x= 2 and y = 3.
L.H.S :
(2/7 x² * 7y) + (2/7x² * 14x)
(2/7 * 2 *2 *7* 3 ) + (2/7 * 2 * 2 * 14 * 2)
= (8/7*21)+(8/7*28)
=(8*3)+(8*4)
= 24 + 32 = 56
R.H.S:
2x²y + 4x^3
= (2* 2 *2 * 3) + (4 * 2 * 2 *2)
= 24 + 32
= 56
Therefore L.H.S = R.H.S
