Question

select the correct answer from each drop-down menu. determine the number and type of solutions for the following quadratic equations using the discriminant. equation number and type of solutions

Answer 1

Equation $y=x^{2} +7x-11$ has two real solutions.

Here are the coefficients:  a=1,b=7,c=11

The discriminating party is: $7^{2}$ -4(1)(-11)=93

Positive, so there are two viable options.

According to the discriminant:

$y=-3x^{2} +x+12$ has two real solutions.

$y=2x^{2} -6x+5$ has zero real solutions.

$y=x^{2} +7x-11$ has two real solutions.

$y=-x^{2} -8x-16$ has one real solution.

What are the benefits of discriminant equation ?

Quadratic functions occupy a special place in the academic curriculum. They are small improvements over linear functions and offer a major break from attachment to straight lines because their values may be readily derived from input values.

The discriminant informs you of the number of quadratic equation solutions or x intercepts for a parabola.
