16? using 16, you have (3x2 + 4)(3x2 + 4) = 9x2 + 24x + 16
To solve equations with absolute values in them, square the absolute value and then take the square root. This works because the square of a negative number is positive, and the square root of that square is the abosolute value of the original number.
About 9.290 square meters.
None does, since there is no polynomial below.
What value, in place of the question mark, makes the polynomial below a perfect square trinomial?x2 + 12x+ ?
16 does that.
There are infinitely many possible answers: c = Â±4x + 33
