Answer:
Step-by-step explanation:
2a^-a-13=2
Subtract 2 from both sides :
2a^2-a-13=2=2-2
2a^2-a-15=0
Factor left side of the equation :
(2a+5) (a-3)=0
Set factors equal to 0 :
2a+5=0 or a-3=0
a=-5/2 or a=3
Answer:
59.4
Step-by-step explanation:
Answer:
1/8^2, 1/2^4 and 1/3^5
Step-by-step explanation:
Answer:
d. Two complex solutions
Step-by-step explanation:
We have been given a trinomial
and we are supposed to predict the type of solutions of our given trinomial.
We will use discriminant formula to solve for our given problem.
, where,
,
,

Conclusion from the result of Discriminant are:
Upon substituting our given values in above formula we will get,


Since our discriminant is less than zero, therefore, out given trinomial will have two complex solutions and option d is the correct choice.
