279 butterflies if I’m correct. 236+128=364 and 364-85 is 279.
The number to be added in an expression <span>x2 + 4x + 3 in order to make it as a perfect trinomial is 1, we need to add 1 to 3 to make it 4 since 4 is a perfect square. Thus, the equation is then x2 + 4x + 4 and the factor of it would bew (x+2)(x+2).</span>
I think the question is 2x/4 - 1/3 + x = 2
So, if I solve for this:
Answer:
