Answer:
(2x+3)(x-7)
Step-by-step explanation:
✯Hello✯
↪ First you are going to want to equally split the equation into separate brackets - I've done this as (2x^2+3)+(-14x-21)
↪ Further factorise this x(2x+3)
↪ From the other bracet factor -7(2x+3)
↪ they have a common term in which we can use to make new brackets
(2x+3)(x-7)
HOPE THIS HELPS

Since there are only two sides (heads & tails) to a coin:
Probability (as fraction) - 1/2
Probability (as percent) - 1/2 x 100 = 50%
Probability (as decimal) - 1 x 50/2 x 50 = 50/100 = 0.5
(P.S. Please mark this answer as the brainliest answer... Thank You)
Answer:
the answer is 1
Step-by-step explanation:
the answer is 1
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
Answer:
(y+9)(y-1)
Step-by-step explanation:
y^2+9y-8y-9
y(y+9)-1(y+9)
(y+9)(y-1)
