Answer: Line up the numbers on the right do not align the decimal points. Starting on the right, multiply each digit in the top number by each digit in the bottom number, just as with whole numbers.
Step-by-step explanation:
You have to divide 10 by


÷

⇒

x

You use a method called "flip-flop and multiply" where you flip the second fraction to multiply

×

⇒

Now divide the numerator (top) by the denominator (bottom)

÷

Now lets check:


÷
Answer: 
×
<span>4x^2 - 36 = 0 ( Original equation )
4x^2 = 36 ( Add 36 to both sides )
x^2 = 9 ( Divide by 4 on both sides )
x = 3 , -3 ( Take the square root of 9 )
Solution set: { +3 , -3 } answer is x = +3 , x = -3</span>
