In simplest radical form, what are the solutions to the quadratic equation 6 = x2 - 10x?
Solution:
The given quadratic equation is:
x2 - 10x - 6 = 0
The roots of a quadratic equation of the ax2 + bx + c are given by the formula below:
Roots = (-b ± √b2 - 4ac)/2a
For the quadratic equation under consideration
a = 1, b = - 10, c = -6
The roots of the equation are:
[-(-10) ± √(-10)2 - 4(1)(-6) ]/ 2(1)
= [10 ± (√100 + 24)] / 2
= [10 ± √124] / 2
= [10 ± √31 × 4 ]/ 2
= [10 ± 2√31] / 2
= 5 ± √31
Hence the two roots are 5 + √31, 5 - √31
In simplest radical form, what are the solutions to the quadratic equation 6 = x2 - 10x?
Summary:
In simplest radical form, the solutions to the quadratic equation 6 = x2 - 10x are 5 + √31, and 5 - √31.
