sorry but your que. is wrong...
question is...
solve for x : √( 6x+7 ) - ( 2x-2 ) = 0
solution:
√(6x + 7) - (2x - 7)= 0
√(6x + 7) = (2x - 7)= 0
squaring both sides :
6x + 7 = (2x - 7)^2
6x + 7 = (2x)^2 - 2(7)(2x) + (7)^2
6x + 7 = 4x^2 - 28x + 49
4x^2 - 28x - 6x + 49 - 7 = 0
4x^2 - 34x + 42 = 0
2 (2x^2 - 17x + 21) = 0
2x^2 - 17x + 21 = 0
2x^2 -14x - 3x + 21 = 0
2x( x - 7 ) - 3( x - 7 ) = 0
( x - 7 ) ( 2x - 3 ) = 0
( x - 7 ) and ( 2x - 3 )
x = 7 and x = 3/2
values of x are: 7 and 3/2...
I hope this may help yuh.....
