Answer:
Step-by-step explanation:
f(-9)=2(-9)²+5(-9)+20
= 162-45+20
= 137
The given trinomial can be factored using the factorization method.
x² -6x +9
= x² -3x -3x +9
= x(x-3) - 3(x-3)
= (x-3)(x-3)
Thus, (x-3)(x-3) is the factored form of the polynomial.
So the correct answer is option D
This is the symmetric property, for you divide 9 to both sides to get x, instead of adding (addition property of equality)
So symmetric property should be your answer
