x = 5i x =-5i
Step-by-step explanation:
x^2+25=0
Rewriting
x^2 - (-25)=0
Writing as the difference of squares
a^2 - b^2= (a-b) (a+b)
where a = x and b = (sqrt(-25)) =±5i
( x-5i) ( x+5i) =0
Using the zero product property
x-5i =0 x+5i =0
x = 5i x =-5i
Steps:
1. Turn the two mixed numbers into improper fractions.
36/5 and 18/5
2. Now divide the fractions by doing the reciprocal with the second fraction and changing the problem to a multiplication problem
36/5 times 5/18
3. 36 times 5=180
5 times 18=90
4. You simplify 180/90 by seeing how many times 180 goes into 90
5. Your answer is 2
