5y - 65xy '5' is a common factor both numbers. Hence 'take it out'. 5(y - 13xy) 'y' is a common factor to both terms, so take it out too!!!! 5y(1 - 13x) Done Factored!!!!!
The GCF is 5y.20y3 = (5y)(4y2)5y2 = (5y)(y)45y = (5y)(9)
2(x - 5y)
Assuming the missing operational sign are pluses, that factors to (3x + 5)(y + 2)
Remember both 16 & 25 are squared numbers. 16 = 4^2 & 25 = 5^2 Hence we can write (4x)^2 - (5y)^2 Remember two squared terms with a NEGATIVE Between them will factor. ( 4x - 5y)(4x + 5y) Note the difference signs. NNB Two squared terms with a positive (+) between them DOES NOT factor.
