Factorize \(4x^2 - 9y^2 + 20x + 25\)

  • A (2x -3y + 5)(2x - 3y - 5)
  • B (2x - 3y)(2x + 3y)
  • C (2x - 3y +5)(2x + 3y + 5)
  • D (2x + 5)(2x - 9y +5)

The correct answer is C. (2x - 3y +5)(2x + 3y + 5)

Given: 4x- 9y+ 20x + 25

Collect like terms: 4x+ 20x + 25 - 9y

(2x + 5)(2x + 5) - 9y

(2x + 5)- (3y)

(2x - 3y +5)(2x + 3y + 5)
