Find the quadratic equation whose solution set is 1/2, 5
Solution:
An equation which has a degree equal to 2 is known as a quadratic equation.
Roots of the quadratic equation are given to be 1/2, 5.
The general form of a quadratic equation is given as
ax2 + bx + c = 0, where a, b are the coefficients of x2 , x and c is a constant.
Since, the zeros are x = 1/2 and x = 5 therefore, the factors are (x - 1/2) and (x - 5)
Thus,
(x - 1/2)(x - 5) = 0
⇒ x2 - (1/2)x - 5x + 5/2 = 0
⇒ x2 - 11x /2 + 5/2 = 0
⇒ 2x2 -11x + 5 = 0
Hence, the quadratic equation with solutions 1/2 and 5 is 2x2 - 11x + 5 = 0.
Find the quadratic equation whose solution set is 1/2, 5
Summary:
The quadratic equation whose solution set is 1/2 and 5 is 2x2 - 11x + 5 = 0.
