Factorise 25(x-y)²-4(x+4)² |
| Answer» FINAL Result =(3x - 7y) • (7x - 3y)STEP-by-step explanation:Step 1 :Equation at the end of step 1 : (25 • ((x - y)2)) - 4 • (x + y)2Step 2 :Equation at the end of step 2 : 25 • (x - y)2 - 4 • (x + y)2Step 3 : 3.1 Evaluate : (x-y)2 = x2-2xy+y2 3.2 Evaluate : (x+y)2 = x2+2xy+y2 Trying to factor a multi variable polynomial :3.3 Factoring 21x2 - 58xy + 21y2 TRY to factor this multi-variable trinomial using trial and error Found a factorization : (3x - 7y)•(7x - 3y)Final result : (3x - 7y) • (7x - 3y)Hope it HELPS you!!!!Mark it as Brainliest ANSWER!!!! | |
