Write out a quadratic trinomial about X, the coefficient of the quadratic term is 2, the constant term is 3, and when x = 1, the value of the polynomial is 6

Let such a quadratic trinomial of X be written as: 2x & # 178; + BX + 3
Then when x = 1, 2 + B + 3 = 6, B = 1
So the quadratic trinomial of X satisfying the meaning of the question is: 2x & # 178; + X + 3
