9x-9y=-9
x-y=-9/9
x-y+1=0.......(1)
4x-3y=-8
4x-3y+8=0....(2)
combining equation we get
(x-y+1)(4x-3y+8)=0
x(4x-3y+8)-y(4x-3y+8)+4x-3y+8=0
4x²-3xy+8x-4xy+3y²-8y+4x-3y+8=0
<u>4x²+3y²-7xy+12x-11y+8=0</u><u> </u><u>is</u><u> </u><u>your</u><u> </u><u>equation</u><u>.</u>
To get the answer to this equation you first cancel out the 6! ;)
(x^2-1)(6x-1) / (x+1)
Then rewrite x^2-1 in the form a^2 + b^2, where a=x and b=1
(x^2-1^2)(6x-1) / (x+1)
Then use the difference of squares!
(x+1)(x-1)(6x-1) / (x+1)
LASTLY cancel "x+1" !
so ur answer is (x-1) (6x-1)
That makes the correct answer to this problem answer choice (D) (x-1) (6x-1)
YW!!! ;)
= x^2 - y^2/6 * 12/(x-y)
= 6x^2 -y^2 * 72/(x-y)
= 6x^2(x-y) -y^2(x-y) * 72
= 6x^3 - 18x^2 -xy^2 + y^3 * 72
= 432x^3 - 1296x^2 -72xy^2 + 72y^3
