Question

Given the quadratic equation:
5n2 =9n2
Find all solutions for n

Answer 1

\[5n^2=9n^2\]

Answer 2

?

Answer 3

yes

Answer 4

Ok

Answer 5

Let get them to one side

Answer 6

5n^2-9n^2

Answer 7

ok

Answer 8

5n^2-9n^2 =0

Answer 9

n^2(5-9)=0

Answer 10

-4n^2=0

Answer 11

so n is 0

Answer 12

ok could it be n=0 or 9/5?

Answer 13

no.
5(9/5)^2\[\neq\]9(9/5)^2

Answer 14

do you use the same formula for this one ? Given the equation: (2x - 87)(x + 5) = 0
Find all solutions for x

Answer 15

When there are in factor(parenthesis) it is actually much easier.
you just look at each factor individually. First one is (2x-87)
2x=87;x=87/2 . the second factor (x+5) is just -5

Answer 16

I get this one! It is easy for real!
