Answer 1

noted, thanks

Answer 2

\[-3x ^{2}-3x+270 =0\]

Answer 3

use quadratic formula here\[x=( -b ^{2}\pm \sqrt{b ^{2}-4ac} ) /2a\]

Answer 4

here a= -3, b= -3, n c= 270

Answer 5

substitute the values then u'll get the answer

Answer 6

got it???

Answer 7

\[x= (-9 \pm \sqrt{9+3240} )-6\]

Answer 8

-6 z divided by the whole term...

Answer 9

\[x= (-9 \pm \sqrt{3249} ) /-6\]

Answer 10

\[x= (-9 \pm 57 ) /-6\]

Answer 11

now seprate the terms -9+57=48 then dvide by -6 u'll get x1=-8

Answer 12

then -9-57=-66... -66/6=-11 which z x2
