Factorizing Algebraic Expressions

The area of a rectangular driveway is 2x² + 15x + 25. What are the possible dimensions of the driveway?

• (x + 1) (2x + 5)

• (x + 5) (2x + 5)

• (x + 10) (2x + 5)

• (2x + 10) (2x + 5)

6x² - ax - 54 = (2x-27)(3x+b) then a + b

• 80

• 81

• 79

• 54

x² + 3x + 2 =(x+2)(x+1)

• True

• False

x² - 15x + 36 =(x-9)(x-4)

• False

• True

x² - 27 x + 72 =(x-24)(x-3)

• True

• False

8x² - 19 x + 6 =(8x-3)(x-2)

• True

• False

x² - 6x - 7 = (x - 7)(x+1)

• True

• False

6x² - 5x - 1 =(3x-1)(2x-1)

• False

• True

x² + (a)   x + 15 = (x+3)(x+5)

x² + (a)   x - 27 = (x+9)(x-3)
