There is no polynomial below.(Although I'll bet there was one wherever you copied the question from.)
x² + 8x + 15 = (x + 5)(x + 3)
What value, in place of the question mark, makes the polynomial below a perfect square trinomial?x2 + 12x+ ?
I think something's missing, but the answer is x(6x - 13)
90
13x(x+3x)
It is (x+2)(x+9) when factored
(x + 2)(3x + 1)
It is the same as xsquared+9x+18 and when factored: (x+3)(x+6)
12
Start by looking for a common factor. Separate this factor, then factor the remaining polynomial.
x3 - 12x2 + 35x = x (x2 - 12x + 35) = x (x - 7) (x - 5)
(-2x3 - 2x2 + 12x) = -2x (x2 + x - 6) = -2x (x + 3) (x - 2)
None does, since there is no polynomial below.
(pā6q) (p2+6pq+36q2)
-(x + 5)(x + 6)
