The solution of the given quadratic equation is x=-2 or x=-3.
The given quadratic equation is x²+5x+6=0.
<h3>What are different methods to solve a quadratic equation?</h3>
The different methods of solving quadratic equations are factoring, completing the square or using the quadratic formula.
By using the splitting middle term method we can solve x²+5x+6=0.
That is, x²+2x+3x+6=0
⇒x(x+2)+3(x+2)=0
⇒(x+2)(x+3)=0
⇒(x+2)=0, (x+3)=0
⇒x=-2 or x=-3.
Therefore, the solution of the given quadratic equation is x=-2 or x=-3.

Answer:
c. 63 toothpicks
Step-by-step explanation:
ok so the base for 16 would be 16 toothpicks
when i first see it that no matter what we would be multiplying 16 by 3 for that triangle shape
16 x 3 = 48
then we would have 15 for the connection toothpicks
48 + 15 = 63
16 would have 63 toothpicks
(-1)^4 is = (-1)(-1)(-1)(-1)= 1
Hope this helps!
