University alberta review (Herkimer County) now let us move on to the second question whether X square plus 6x plus 15 has zeros or not so let us move on to the solution given expression is X square plus 6x plus 15 the Middletown 6x can be written as x squared plus 2 times 3 times X plus 15 can be written as 9 plus 6 so this is X square plus 2 times 3 times X plus -3 square plus 6 therefore this expression is of the form a squared plus 2 a B plus B Square so this can be written as X plus 3 whole square plus 6 for an expression to have a 0 there should exist a value of x for which the whole expression becomes 0 but for this expression for no value of x this expression becomes 0 therefore x squared plus 6x plus 15 has no zero Dominican College, Orangeburg. https://PaperHelp.space
