Given : (2x + 7) (5x + 9) - (4x² + 1) (x – 3)
To Find : Simplify
Solution:
(2x + 7) (5x + 9) - (4x² + 1) (x – 3)
Apply distributive property
= 2x(5x + 9) + 7(5x + 9) - 4x²(x - 3) - 1(x - 3)
= 10x² + 18x + 35x + 63 - 4x³ + 12x² - x + 3
= -4x³ + 10x² + 12x² + 53x - x + 63 + 3
= -4x³ + 22x² + 52x + 66
(2x + 7) (5x + 9) - (4x² + 1) (x – 3) = -4x³ + 22x² + 52x + 66
