Remember you can do anything to an equation as long as you do it to both sides
alrighty
distribute, rmember that a(b+c)=ab+ac
-3x-9=-3x-3-5
combine like terms
-3x-9=-3x-8
add 3x to both sides
-9=-8
false
no solution
answer is no solution
(-2,3) (4,-5) (2,4) you change the x value to to its opposite.
Answer:m=-1
Step-by-step explanation:
M=-(4+m)+2
M=-4-m+2
m+m=-4+2
2m=-2
m=-1

.The polynomial simplifies to an expression that is a____
A.quadratic
B.liner
C.constany
A.trinomial
B.binomial
C.monomial
with a degree of____
A.1
B.2
C.0
Solution:
A polynomial is an expression involving operations of addition, subtraction, multiplication, exponents which consists of variables and their coefficient. A trinomial is a polynomial consisting of three terms, while a binomial consist of two terms and a monomial consist of one term.
The degree of a polynomial is the highest degree of any of the terms of the polynomial. If it has a degree of 0 it is a constant, a degree of 1 it is linear while for a degree of 2 it is quadratic.
(-5x² - 2x + 4) + (8x² - x - 1) + (x + 2)(x - 5)
= (-5x² - 2x + 4) + (8x² - x - 1) + (x² -5x + 2x - 10)
= (-5x² - 2x + 4) + (8x² - x - 1) + (x² - 3x - 10)
= (-5x² + 8x² + x² - 2x - x - 3x + 4 - 1 - 10)
= 4x² - 6x - 7
Therefore:
.The polynomial simplifies to an expression that is a quadratic trinomial of degree 2.
