Which expression is equivalent to 2x^2-18

a) 2x-3)^2

b) 2(x-3)^2

c) (x-9) (x-9)

d) 2(x+3)(x+3)

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 )
