Answer:
Step-by-step explanation:
Answer : 
(1) 
Use FOIL method to mulitply (3x – 5)(3x – 5)

(2) 
Use FOIL method to mulitply (3x - 5)(3x + 5)

(3) 
Use FOIL method to mulitply -(3x + 5)(3x + 5)

(4)

Answer:
x² + 2x - 48
Step-by-step explanation:
( x + 8 ) ( x - 6 )
= x ( x - 6 ) + 8 ( x - 6 )
= x*x - 6*x + 8*x + 8*( - 6 )
= x² - 6x + 8x - 48
= x² + 2x - 48
