Answer:
A.
Step-by-step explanation:
you have to find the discriminant
b²-4ac for each equation
if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots
if discriminant = 0 there is only one solution
if discriminant > 0 two real solutions
for your given problems
A. discriminant =(-2)²-4*2*15 will be negative
Where is the question. though
The answer is -14
Explanation:
x - 8 = 2x + 6
We move all term to the left
x - 8 - ( 2x + 6 ) = 0
We get rid of parentheses
x - 2x - 6 - 8 = 0
We add all the numbers together, and all the variables
-1x - 14 = 0
We move all terms containing x to the left, all other term to the right
-x = 14
x = 14/-1
x = -14
Answer:
a) -3
b) 5
c) 7
d) 4
Step-by-step explanation:
We have the function 
a) We need to find the coefficient of 
.
This means that we need to find out what number is alongside the in this equation. From the function, we can find that it is -3
b) Now we need to find the degree of 
. Recall that the degree refers to the highest power of x that is present. As 
is the largest power, our degree would be 5.
c) The constant term refers to the number within the function that does not have any x's with it. In this function, that number would be 7.
d) Now we need to find the number of terms. For this one, we just need to count how many terms are separated by + or - signs. There are 4 in this function.
