Question

1. (x - 7)(x + 2)
2.( m +9)(m - 8)
3. (-x+2)(3-x)
4. (3x + 7)(x + 4)
5. (2x - 5)(3x + 2)
6. (5x - 4y)5x + 4y
7. (3x +2y)(3x-y)​

Answer 1

(x - 7)(x + 2)

x² - 5x - 14

(m +9)(m - 8)

m² + m - 72

(-x + 2)(3 - x)

(2 - x)(3 - x)

6 - 5x + x²

(3x + 7)(x + 4)

3x² + 12x + 7x + 28

3x² + 19x + 28

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

6x² + 4x -15x - 10

6x² - 11x - 10

(5x - 4y)(5x + 4y)

25x² - 16y²

(3x +2y)(3x-y)​

9x² - 3xy + 6xy - 2y²

9x² + 3xy - 2y²
