Determine the $x$-intercept(s) of the quadratic function $f ( x ) = x ^ { 2 } - 10 x + 26$.
A) $( 0,0 ) , ( 4,0 )$
B) $( 5,0 ) , ( 10,0 )$
C) $( 7,0 ) , ( 2,0 )$
D) $( 0,0 ) , ( 2,0 )$
E) no $x$-intercept(s)

Question

Quizplus · Accepted Answer

The quadratic function $f(x) = x^2 - 10x + 26$ does not have real roots, as its discriminant $b^2 - 4ac = 10^2 - 4 \times 1 \times 26 = 100 - 104 = -4$ is negative. Therefore, there are no $x$-intercepts.
