How is multiplying fractions the same as multiplying whole numbers and different

gtnhenbr [62]

Well one similarity is that since you have to multiply, integer rules still apply and that you can also multiply variables. A difference is that with fractions, you have to make a number into an improper fraction rather than just the regular way which would most likely be the whole number with a decimal.

Find the solutions of the given equation. <br><br> 25x^2+64=289

AleksAgata [21]

Answer:

Step-by-step explanation:

Start by subtracting 64 from both sides:

$25x^2=225$

Factor this by taking roots. Divide both sides by 25 first:

$x^2=9$

We "undo" a square by taking the square roots of both sides. Taking the square root leaves the possibilities of both the positive and negative roots of 9. Therefore, the solutions to this are

$x=\sqrt{3},-\sqrt{3}$
