Step Type Explanation Answer

1

Problem

Find the roots of the quadratic equation:
\$ (x)(x-1) = 3 \$

2

Step

the equation is converted to

\$ax^2+bx+c=0\$

3

Step

the equation is

\$ x^2 - x - 3 = 0 \$

4

Step

Since the equation is in the form of

\$ax^2+bx+c=0\$

5

Formula:

formula

\$ x = (-b \pm \sqrt (b^2 - 4ac))/(2a) \$

6

Step

the values

\$ a = 1, b = -1 , c = -3\$

7

Step

converting the equation into formula by substituting the values

\$ x = (-(-1) \pm \sqrt ((-1)^2 - 4(1)(-3)))/(2(1)) \$

8

Step

Solving the roots of the equation

\$ x = (1 \pm \sqrt (1 + 12))/2 \$

9

Step

after solving the roots of the equation

\$ x = (1 \pm \sqrt (13))/2 \$
