Answer 1

x² + 7x + 6 = (x + 6) (x  + 1)

x²  + x - 42= (x + 7) (x  - 6)

(x + 2)(x + 6) =  x²  + 8x + 12

(x - 4)(x + 7) = x² + 3x -28

(x + 7)(x - 2) = x² + 5x -14

(2x - 6)² = (2x)² - 2 (2x) (6) + (6)² = 4x² - 24x + 36

( x + 6y)(x  - 6y) = (x)²  - (6y)² = x² - 36y²

(x + 8)(x  -15) = x²  - 7x  - 120

602² = (602) (602) = 362404

45² - 35² = (45 + 35) ( 45 - 35) = (80) (10) = 800

303² = (303) (303) = 91809

102² - 98² = (102 + 98) (102 - 98) = (200) (2) = 400

x² - 169 = ( x + 13) ( x - 13)

25x² - 961 = (5x +31) (5x - 31)

x² + 6x + 5 = ( x + 5) (x + 1)

x² + x + 8 = ?

x² - 22x + 96 = (x -16) (x  - 6)

x² - 18x -19 = (x -19) (x + 1)

x² - 26x +165 = (x  - 15) ( x  - 11)

x² - 5x -150 = (x  -15) (x  + 10)
