SOLUTION: Is this a quadratic equation? x + 3 = the square root of 44 + 4x.
(NOTE: 44 + 4x is all under the radicand. I don't know how to factor it so that I can subtract 3 from both
Question 3161: Is this a quadratic equation? x + 3 = the square root of 44 + 4x.
(NOTE: 44 + 4x is all under the radicand. I don't know how to factor it so that I can subtract 3 from both sides. Would very much appreciate problem detailed on the whole)
You can put this solution on YOUR website! x=-7 is an invalid answer,
since left hand side = x+3 = - 4
but the right hand sqrt(44 + 4x) = sqrt(44-28) = 4
