F(x)=6x^2+10x-1

What is the value of the discriminant of f?

How many distinct real number zeros does f have?

Two different real solutions

Step-by-step explanation:

we know that

In a quadratic equation of the form

The discriminant D is equal to

Equate f(x) to zero

so

we have

substitute

The value of D is greater than zero

That means ----> The quadratic equation has two different real solutions

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
