In a trinomial the first and third terms are perfect squares and the middle term is +14xy. Then the trinomal is what?

Dear student
We know that  a trinomial consists of 3 terms Given that first and third terms are perfect squaresLet first term=7x2and second term=7y2Then trinomial=7x2+14xy+7y2=7x2+2×7x×7y+7y2=7x+7y2using a+b2=a2+b2+2ab
