Answer:
The first option .
Step-by-step explanation:
To have exactly 2 real and two non real solutions, the degree of the polynomial must be a degree 4. Degree is the highest exponent value in the polynomial and is also the number of solutions to the polynomial. This polynomial ha 2 real+2 non real= 4 solutions and must be . This eliminates the bottom two solutions.
In order to have two real and two non real solutions, the polynomial must factor. If it factors all the way like
This means x=0, 10, -10 are real solutions to the polynomial. It has no non real solutions. This eliminates this answer choice.
Only answer choice 1 meets the requirement.
Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
Solve. −3/5x+1/5>7/20 Drag and drop a number or symbol into each box to show the solution
we have
Solve for x
Multiply by 20 both sides
subtract 4 both sides
divide by -12 both sides
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
simplify
