Question: How do you solve \[4{{x}^{2}}-16=0\]?...
How do you solve 4x2−16=0?
Explanation
Solution
We have to solve the problem using a quadratic formula. First we have to substitute the coefficients in the quadratic formula. Next we have to simplify it to get the desired results. Here we will consider the middle term as zero because it is not present in the given equation.
Complete step by step answer:
Given equation is
4x2−16=0
The quadratic formula for the standard equation is ax2−bx+c=0 is
y=2a−b±b2−4ac
So using our equation we have to find a,b,c values.
We will get values as
