Formula Formula A polynomial with degree 2 is called a quadratic polynomial. A quadratic equation can be simplified to the standard form: ax² + bx + c = 0 Where, a ≠ 0. A, b, c are coefficients. c is also called "constant". 'x' is the unknown quantity
Expert Solution & Answer
To determine
To find the side length of a square.
Answer to Problem 22P
The side length of a square is 14ft .
Explanation of Solution
Given:
The area of square is 196ft2
Calculation:
Let the side length of a square be x
So, the area of square is equals to x2
Also it is given that area of square is 196ft2
Area=x2=196x2=196Taking square root both sidex=196=14
