(9-15)/(-2+4)= -6/2 = -3
-3 is the slope
-7x^2 - 6x^2 + 3x + 5x - 5 + 2
-13x^2 + 8x - 3
Answer:
-2 and -6 is the correct answer
Answer:

Step-by-step explanation:
Multiply out
in order to find out which expression it is equivalent to.
1) Since the whole quantity is squared, write it out as
.

2) Multiply binomials by using the FOIL method. Multiply the terms that are listed first in each binomial, then the ones that are listed outermost when looking at both binomials, then innermost, and finally the last terms listed in each binomial. Simplify and combine like terms.


3)
, so
must be
. Thus,
is equivalent to -1. Knowing this, simplify and combine like terms.


Thus, it is equivalent to
.
Take the logarithm of both sides. The base of the logarithm doesn't matter.


Drop the exponents:

Expand the right side:

Move the terms containing <em>x</em> to the left side and factor out <em>x</em> :


Solve for <em>x</em> by dividing boths ides by 5 log(4) - log(3) :

You can stop there, or continue simplifying the solution by using properties of logarithms:



You can condense the solution further using the change-of-base identity,
