Question

Fill in the blank/s:

In order to solve x²= 4x + 1 by the quadratic formula, we use a =______ , b =_______ , and c =__________ ?

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

Step 1

We will write x²= 4x + 1 as x²- 4x - 1 =0

Then we compare it with ax² +bx + c = 0

So, we get, a=1, b=-4 and c=-1

Step by step
