Hello!
When solving a quadratic equation, we should begin by confirming that the right side is equal to 0. The equation above, however, contains a 2 on the right side.
Therefore, the most logical first step would be to subtract 2 from both sides, leaving the ride side equal to 0.
I hope this helps!
Answer:
Step-by-step explanation
In the form ax^2+bx+c
a x c should equal two factors of b
However, in this equation
1 x 19 has no factors that = 10
so you must use the Quadratic Formula which is,
x = 
so the answer should be
x = 
x = 
x =
and x = 
Answer:
c. results in either of two directions can lead to rejection of the null hypothesis.
Step-by-step explanation:
A two tailed test is performed when we want to test if there is statistically significant difference from the null state. That means that if the statistic value is significantly higher or significantly lower, we will reject the null hypothesis. Both tails have rejection areas.
3^7 when you are multiplying numbers with the same base add the exponents.
