Question

Simplify: ((4y^2 - 13y + 3) / (2y^2 - 5y - 12)) * ((2y^2 + 9y + 9) / (16y^2 - 1)) * ((y^2 + 3y - 28) / (y^2 - 9))

Answer 1

waooo

Answer 3

thats for a picture of it

Answer 4

factor everything !!

Answer 5

it is to be simplified, not factored.

Answer 6

\[\large\rm \frac{ 4y^2-13y+3 }{ 2y^2-5y-12 } \times \frac{ 2y^2+9y+9 }{ 16y^2-1 } \times \frac{ y^2+3y-28 }{ y^2-9 }\]

Answer 7

yes but you have to factor all quadratic equations

Answer 8

it has been awhile since i have last did some math, or even used math in my daily life. I sadly also have a horrible memory, so i cant remember how to do this. thankfully though, i am a fast learner.

Answer 9

alight
4y^2 -13y +3
there are 3+ ways to factor quadratic equations
easy one is to find two number if you multiply them you should get product of AC
and if you add or subtract them you should get middle term

Answer 10

abc values are \[\large\rm Ax^2+Bx+C=0\]

Answer 11

hmmmm

Answer 12

maybe it is just me, but. . . i dont see how this can apply to the current equation, because the equation i posted has 3 fractions multiplying with eachother, and from what you posted. . . it is a single line with a equal sign.

Answer 13

okay let's do this one together
\[\large\rm 4y^2 -13y +3 \]\[\large\rm Ax^2+Bx+C \]
A=4
C =3
multiply AC= 12
now find two number if you multiply them you should get 12 and if you add or subtract them then you should get -13

Answer 14

i know we have to factor all quadratic equation one by one
4y^2 -13y +3
^^so that equation is at the numerator of first fraction

Answer 15

how does A=4 and C=3?

Answer 16

Quadratic equation
Ax^2+Bx+C
A is the leading coefficient and C is the constant term
b = middle term

Answer 17

4y^2 -13y +3
so what is leading coefficient here and what is constant term ?

Answer 18

A= 4 B=-13 c= 3?

Answer 19

yes that's right

Answer 20

multiply AC= 4 times 3 = 12
B=-13
now find two number if you multiply them you should get 12 and if you add or subtract them then you should get middle term which is -13

Answer 21

sorry, my computer died. lol

Answer 22

what do you mean by "find two number"?

Answer 23

what method did you learn 'n school ?

Answer 24

i cant remember, it has been some time now... like 3-10 weeks

Answer 25

what two number you should multiply to get =12
1st number TIMES 2nd number = 12
what are the numbers ?

Answer 26

3 & 4

Answer 27

yep
3 times 4 = 12
but 3+4 = -13 ??
2 times 6 = 12 but 2 +6 isn't equal to -13

-12 times -1 = 12 correct -12 -1 = -13 ? right two numbers are
-12 aand -1 when you multiply them you will get 12 and when you add them u will get -13 correct thats what we need

Answer 28

carry down first and last term
write those two number in middle now apply group method
