To subtract fractions, you first need to find a common denominator. The common denominator should be a multiple of both denominators. We can use 30 because it is a multiple of both 10 and 3.

Now that we have 30 on the bottom, we need to multiply the numerators by the same amount we multiplied the denominator by to keep the fractions proportional.

First 7/10... To turn 10 into 30 we had to multiply by 3. Do the same to the 7. We now have 7*3 = 21.

Then -5/3... To turn 3 into 30 we had to multiply by 10. So -5*10 = -50.

Now subtract the numerators.

21 - (-50) = 21 + 50 = 71.

So the answer is 71/30

Factor completely 3X^2 -25​
Dominik [7]

In order to factor a polynomial, you have to find its roots

x_1,\ x_2,\ldots,x_n

So that you can factor it as

p(x)=(x-x_1)(x-x_2)\cdots(x-x_n)

So, in this case, we're looking for the solutions of

3x^2-25=0 \iff 3x^2=25 \iff x^2 = \dfrac{25}{3} \iff x=\pm\sqrt{\dfrac{25}{3}}=\pm\dfrac{5}{\sqrt{3}}

So, the polynomial can be written as

3x^2-25 = \left(x-\dfrac{5}{\sqrt{3}}\right)\left(x+\dfrac{5}{\sqrt{3}}\right)
