Which value must be added to the expression x^2+12x to make it a perfect square trinomial a:6 b:36 c:72 d:144
2 answers:
The answer would be 36. Why?
Because in the equation we would need to do (x + 6)(x + 6) to get a perfect square trinomial.
And 6 * 6 is 36.
So the whole equation would be: x^2 + 12 + 36.
Hope this helped! c:
The quadratic expression uses the following formula:
The expression is missing the variable of c, and it is a perfect square trinomial.
To find c in a perfect square trinomial, we will use the following formula:
The value of b in this expression is 12. Plug this value into the formula:
36 must be added to make this trinomial a perfect square.
