Step-by-step explanation:
Given bi-quadratic equation is:
Substituting
given bi-quadratic equation reduces in the form of following quadratic equation:
Let us factorize the above quadratic equation:
Since square root of a negative number cannot be found, so:
![CASE\: (2)\:\\When\: a =5 \implies x^2 =5\\\therefore x=\pm \sqrt{5}\\](https://tex.z-dn.net/?f=CASE%5C%3A%20%282%29%5C%3A%5C%5C%3C%2Fp%3E%3Cp%3EWhen%5C%3A%20a%20%3D5%20%5Cimplies%20x%5E2%20%3D5%5C%5C%3C%2Fp%3E%3Cp%3E%5Ctherefore%20x%3D%5Cpm%20%5Csqrt%7B5%7D%5C%5C%3C%2Fp%3E%3Cp%3E)
You must always use the order of operations also known as PEMDAS meaning multiplication and division come before adding and subtracting for example when solving 2+2÷2 if not follwing PEMDAS it is 2 When you do it the correct way using PEMDAS it will be 3
Answer:
well that is a pretty good deal i might have to go there
Step-by-step explanation:
Well you can put 4/5 in a decimal form by dividing it
which is 0.8
Answer:
x = 2.
Step-by-step explanation:
The corresponding sides are in the same ratio (because they are similar).
So 5x / 5 = 4 /x
5x^2 = 20
x^2 = 4
x = 2.
