Question

For what value of m is x square minus mx +2 have the factor x-1

Answer 1

SOLUTION:-

x² - mx + 2 = 0

since x- 1 is factor of above equation

•°• put x = 1

(1)² - m(1) + 2 = 0

1 - m + 2 = 0

-m + 3 = 0

3 = m

m = 3

value for m is 3

More information

The above equation is a quadratic polynomial. The equation involving one variable and having 2 as the maximum index of the

variable is called the quadratic equation.

General form is ax2 + bx + c = 0. where a, b, c are real numbers and ’a ’ is non zero.

Quadratic polynomial can be solved by Factorization, formula and by completing the square method.
