The roots of the equation x²-3✓2x +4=0 are :
(a) integers
(b) rational but not integral
(c) negative irrational numbers
(d) positive irrational numbers​

Answer 1

Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
