= x (x - 3 ) 5 (x - 3)
= (x +5 ) (x - 3)
b. x² + 8x +16 = x²+ 4x +4x +16
= x ( x +4) 4( x+4)
= (x + 4) ( x+ 4 )
c. x² - 5x - 14 = x² -7x +2x - 14
= x (x - 7) 2 (x- 7)
= (x+2) ( x - 7)
d. 8x² +2x - 3 = 8x² - 4x +6x -3
= 4x (2x - 1) 3( 2x -1)
= ( 4x +3 ) (2x - 1)
e. 6y² + 8y - 8 = 6y² - 4y + 12y -8
= 2y ( 3y -2) 4 ( 3y - 2)
= (2y +4) (3y - 2)
