Options 3, 4 and 5

Step-by-step explanation:

Given:

F(x) = x³ + 3x² - 25x - 75

Factor the given function:

F(x) = x³ + 3x² - 25x - 75

⇒ take x² a common from (x³ + 3x²) and (-25) a common from (- 25x - 75)

F(x) = x²(x+3) - 25 (x+3)

⇒ take (x+3) as a common

F(x) = (x+3) (x² - 25)

(x² - 25) = (x-5) (x+5)

∴ F(x) = (x+3) (x-5) (x+5)

The answer are options 3, 4 and 5

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)
