Answer:
(3x−5y)⋅(5x+3y)
Step-by-step explanation:
STEP 1 :
Equation at the end of step 1
((15 • (x2)) - 16xy) - (3•5y2)
STEP 2 :
Equation at the end of step 2 :
((3•5x2) - 16xy) - (3•5y2)
STEP 3 :
Trying to factor a multi variable polynomial
3.1 Factoring 15x2 - 16xy - 15y2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (3x - 5y)•(5x + 3y)
Final result :
(3x - 5y) • (5x + 3y)
