Subtract the second expression from the first.i. (6x² + 7xy + 16y²);

1.	Subtract the second expression from the first.i. (6x² + 7xy + 16y²); (16x² – 17xy) ii. (4x + 16z); (19y – 14z + 16x)
Answer» iv. (6x² + 7xy + 16y²) – (16x² – 17xy) = 6x² + 7xy + 16y² – 16x² + 17xy = (6x² – 16x²) + (7xy + 17xy) + 16y² = -10x² + 24xy + 16y² v. (4x + 16z) – (19y - 14z + 16x) = 4x + 16z – 19y + 14z – 16x = (4x – 16x) – 19y + (16z + 14z) = -12x – 19y + 30z

Subtract the second expression from the first.i. (6x² + 7xy + 16y²); (16x² – 17xy) ii. (4x + 16z); (19y – 14z + 16x)

Answer»

iv. (6x² + 7xy + 16y²) – (16x² – 17xy)

= 6x² + 7xy + 16y² – 16x² + 17xy

= (6x² – 16x²) + (7xy + 17xy) + 16y²

= -10x² + 24xy + 16y²

v. (4x + 16z) – (19y - 14z + 16x)

= 4x + 16z – 19y + 14z – 16x

= (4x – 16x) – 19y + (16z + 14z)

= -12x – 19y + 30z
