Which expression is equivalent to 9 x squared minus 2 y + 3 x squared minus 3 y? 6 x squared minus y + 6 x squared minus 5 y
6 x squared minus y + 3 x squared minus 4 y
10 x squared minus 4 y + 2 x squared minus y
11 x squared + 2 y + x squared minus 3 y

Ans1wer: 10x^2

Step-by-step explanation:

10x^2+2x^2=12x^2 and -4y-y=-6y

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
