Question

Determine the roots of the equation 73 x2 - 2x - 13 = 0​

Answer 1

Step-by-step explanation:

 1.1     Factoring  x2-2x-13 

The first term is,  x2  its coefficient is  1 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  -13 

Step-1 : Multiply the coefficient of the first term by the constant   1 • -13 = -13 

Step-2 : Find two factors of  -13  whose sum equals the coefficient of the middle term, which is   -2 .

     -13   +   1   =   -12     -1   +   13   =   12

Observation : No two such factors can be found

Answer 2

Answer:

you can learn from this example

x² - 2x - 13 = 0

x = unknown

a = 1

b = -2

c = -13

Substitute the values of the coefficients a, b, and c into the quadratic formula

Quadratic Equation - Substitute the values of the coefficients a, b, and c into the quadratic formula
