Answer:
here, x = 3 and y = -4 (given)
= yx² ( x - y²) + xy² ( 4yx - 2x²) - yx³ ( 1- 2y)
= -4 × 3² ( 3 - (-4) + 3 × -4² (4 × -4 × 3 - 2× 3²) - (-4)
3³ ( 1 - 2 × -4)
= - 36 × -7 + 48 ( -48 - 18 ) + 4 × 27 ( -7)
= 252 +48 - 30 + 107 -7
= 300 - 30 + 107 - 7
= 270 + 107 -7
= 270 + 100
= 370 ANS
hope it will be an assisting answer
