Question

under root 3 x square - 7 x minus 30 minus again under root 2 x square - 7 x minus 5 is equals to x minus 5 solve for x

Answer 1

    √3x² - (7x - 30 - √2x²) - ( 7x - 5) = x - 5
or,√3x² - 7x+30+√2x² - 7x+5 = x - 5
or,√x² - 14x - x = - 5 - 35 = - 40
or,x - 14x - x = - 40
or, - 14x = - 40
∴x = 40/14
     =2.86 [approx]
