Answer:
4. (5x - 1) (2x + 3)
= 10x² + 15x - 2x - 3
= 10x² + 13x - 3
Standard form = 10x² + 13x - 3
Leading term = 10x²
Leading coefficient = 10
Degree = 2
Constant = -3
5. (4x - 3) (4x + 4)
= 16x² + 16x -12x - 12
= 16x² + 4x - 12
Standard form = 16x² + 4x - 12
Leading term = 16x²
Leading coefficient = 16
Degree = 2
Constant = -12
6. x⁴ + 3x - 5x⁵ - 1
= -5x⁵ + x⁴ + 3x - 1
Standard form = -5x⁵ + x⁴ + 3x - 1
Leading term = -5x⁵
Leading coefficient = -5
Degree = 5
Constant = -1
hope this helps
