If there is only one solution, at x=-3, then the factor of (x+3) must be repeated. The equation must be equivalent to
... (x +3)² = 0
This multiplies out to give
... x² +6x +9 = 0
The value of m is 6.

For finding the square of a binomial, you can either use the special form you have memorized:
... (x +a)² + x² +2ax + a²
or you can use the distributive property.
... (x +a)² = x(x +a) +a(x +a)
... = x² +ax +ax +a² = x² +2ax +a²
Simply the bottom to 2(x-3)
Then the top factors down into (x-3)(x+4)
The (x-3) term cancels out
You are left with ANSWER: (x+4)/2
thank you hope this helps
Answer:
the answer is 67 square inches.
Answer:
Rounded, 5.4
Explanation:
5^2 + 2^2 = c^2
25 + 4 = c^2
29 = c^2
5.4 = c
The answer is six because you have to subtract the upper and lower quartile which are 18 and 16 in this case
