Question

4z^2-16+15/2z^2+z-15 simplifed form? 4z^2-16+15/2z^2+z-15 simplifed form? @Mathematics

Answer 1

try to solve it by factorizing numerator and denominator first

Answer 2

yasmeen i feel i sud tell u full procedure

Answer 3

u think u can explain i t actually that would be great?

Answer 4

is their z in middle term of the numerator

Answer 5

4z^2 - 16 + 15 or, 4z^2 -16z + 15

Answer 6

OHHH
i wrote it wrong....... 4z^2-16+15/2z^2+z-15

Answer 7

I did it again!

Answer 8

Oh no its right

Answer 9

\[\frac{4z^2 -16 + 15}{2z^2 + z-15}\]
\[\frac{4z^2 -1}{2z^2 + 6z-5z-15}\]
\[\frac{(2z)^2 -1}{2z(z + 3)-5(z+3)}\]
\[\frac{(2z+1)(2z-1)}{(z + 3)(2z-5)}\]

Answer 10

if that was right so it is right

Answer 11

see i have choices and all the chioces look somthing like this 2z-3/z+3

Answer 12

2z-3/z+3.....
2z+3/z+3...
2z+3/z-3....
2z-3/z-3..... these are my choices

Answer 13

\[\frac{4z^2 -10z -6z + 15 }{2z^2+6z-5z-15}= \frac{(2z-5)(2z-3)}{(2z-5)(z+3)} =\frac{2z-3}{z+3}\]

Answer 14

thanks and good explaintion

Answer 15

u think u can help me with a muliplication like this problem?

Answer 16

if u want to learn then only otherwise how can any1......think of it ????

Answer 17

1/5xy times 10x^2/7y

Answer 18

\[\frac{2x}{7y}\]

Answer 19

i was thinking it was 7/50x^3

Answer 20

xy is not in the denominator

Answer 21

mmmm ok

Answer 22

can u walk me through this one because i dont think im understanding/// 12y4/88x^3 times 6x^8/20y^6

Answer 23

\[\frac{xy}{5} \times \frac{10x^2}{7y} = \frac{2x^3}{7}\]

Answer 24

oh so its like cross mulitplying?

Answer 25

its not 88! its just 8x^3

Answer 26

\[\frac{12y^4}{8x^3} \times \frac{6x^8}{20y^6} = \frac{9x^5}{20y^2}\]

Answer 27

thanks!\
