If the discriminant is negative then the quadratic has
zepelin [54]

Answer:

No <em>real</em> solutions (or has two complex roots)

Step-by-step explanation:

The discriminant, <em>b</em>² - 4<em>ac</em>, is the expression (<u><em>radicand </em></u>) of the quadratic equation:

x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}.

The value of the discriminant determines the <u>nature</u> and the <u>number of solutions</u> given by the quadratic equation.

A discriminant with a negative value (or b² - 4ac < 0 ) means that the quadratic equation has no real solutions or two complex solutions. Quadratic equations with a negative discriminant also have no x-intercepts; thus, its graph will not cross the x-axis.

Let f(x) = 5x2 – 4x and g(x) = 5x + 1.
Nastasia [14]

f(x) = 5x^2 - 4x

g(x) = 5x + 1

Therefore f - g = 5x^2 - 4x - (5x + 1)

= 5x^2 - 4x - 5x -1

= 5x^2 -9x - 1


Hope it helps :)
