Factor completely: 5ab + 3ay + 5b + 3y (5b + 3y)(a + 1) <----- (5b − 3y)(a + 1) (5b + 3y)(a − 1) Prime Factor completely: 21x3 + 35x2 + 9x + 15 (3x − 5)(7x2 − 3) (3x − 5)(7x2 + 3) (3x + 5)(7x2 − 3) (3x + 5)(7x2 + 3) <---- Factor completely: 3ab − 5ax + 9b − 15x (3b + 5x)(a + 3) (3b − 5x)(a + 3) <----- (3b − 5x)(a − 3) Prime
yup perfect:)

Well Done @mikaa_toxica13 :)
Factor completely: 4xy + 9x + 24y + 54 (4y − 9)(x − 6) (4y − 9)(x + 6) <---- (4y + 9)(x − 6) (4y + 9)(x + 6) Factor completely: 9ab + 12ax − 6b − 8x Prime (3b − 4x)(3a − 2) (3b + 4x)(3a − 2) (3b + 4x)(3a + 2) <----- Factor completely: 5ab(x + 6) − 4(x + 6) Prime (x + 6)(5ab + 4) (x + 6)(ab) <----- (x + 6)(5ab − 4)
sorry to say but this time u didnt get them right:(
:/ okay can u tell me how to do them and which answers are right ?
Factor completely: 4xy + 9x + 24y + 54 (4y − 9)(x − 6) (4y − 9)(x + 6) <---- (4y + 9)(x − 6) (4y + 9)(x + 6) In the question all the terms are positive. but in ur answer there is a minus sign.
so it would be the last one ? (4y + 9)(x + 6)
(4y + 9)(x + 6) =4y*x+4y*6+9*x+9*6 =4xy+24y+9x+54 yup it is:)
(3b + 4x)(3a − 2) for the second one. i got the arrow in the wrong place lol
ya it is right:)
okay and for the last one ? i didnt really understand it at all.
5ab(x + 6) − 4(x + 6) Let us assume that x+6=y for simplicity then u will have 5aby-4y factor out y and then replace it with x+6
oh, so its the last one ?
yup:)
thank u sooo much !
welcome:)
