Question

What is the result of isolating x^2 in the equation below? 10x^2-36y^2=100???? please help

Answer 1

first isolate 10x^2
10x^2 = 36y^2 + 100
Divide both sides by 10
x^2 = 3.6y^2 + 10

Answer 2

Answer:

$x^2=10+\frac{18y^2}{5}$

Step-by-step explanation:

If you really want to get x^2 by itself the first step is to add 36y^2 on both sides giving you:

$10x^2-36y^2=100$

$10x^2-36y^2+36y^2=100+36y^2$

$10x^2+0=100+36y^2$

$10x^2=100+36y^2$

Now you divide both sides by 10:

$x^2=\frac{100+36y^2}{10}$

You could separate the fraction:

$x^2=\frac{100}{10}+\frac{36y^2}{10}$

You can reduce both fractions:

$x^2=10+\frac{18y^2}{5}$
