Give me step by step explanation fast I will mare you as brainlest the question is Factorise |
|
Answer» is the QUESTION ok Step-by-step explanation:STEP1:Equation at the end of step 1 (9 • ((x + y)2)) - 16 • (x - 3y)2STEP2:Equation at the end of step 2 9 • (x + y)2 - 16 • (x - 3y)2STEP3: 3.1 Evaluate : (x+y)2 = x2+2xy+y2 3.2 Evaluate : (x-3y)2 = x2-6xy+9y2 STEP4:Pulling out like terms 4.1 Pull out like factors : -7x2 + 114xy - 135y2 = -1 • (7x2 - 114xy + 135y2) Trying to factor a multi VARIABLE polynomial : 4.2 FACTORING 7x2 - 114xy + 135y2 TRY to factor this multi-variable trinomial using trial and error Found a factorization : (x - 15y)•(7x - 9y)FINAL result : (15y - x) • (7x - 9y) |
