What are the exact solutions of x2 + 5x + 1 = 0? (5 points)

Rus_ich [418]

Answer:

$x=\frac{-5\pm\sqrt{21} }{2}$

Step-by-step explanation:

We use the quadratic formula here which says for a quadratic equation $ax^2+bx+c=0$ .

$x= \frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Now in our case

$a=1\\b=5\\c=1$

so we have:

$x=\frac{-5\pm\sqrt{5^2-4(1)(1)} }{2(1)} =\frac{-5\pm\sqrt{21} }{2}$

$\boxed{x=\frac{-5\pm\sqrt{21} }{2} }$

Which are our solutions.

X²-x-6<br> What is hcf of the polynomial

Eva8 [605]

Answer:

the highest common factor of the polynomial is (x + 2) (x - 3)

Step-by-step explanation:

The computation of the highest common factor of the polynomial is as follows:

According to the question, the following equation is given

' $x^2 - x - 6$

Now do the factorization

$x^2 -3x + 2x - 6$

x(x - 3) +2 (x - 3)

(x + 2) (x - 3)

hence, the highest common factor of the polynomial is (x + 2) (x - 3)

The same is to be considered

alex needs to varnish the top and the bottom of a dozen rectangular wooden planks.The planks are 8 feet long and 3 feet wide.Eac

Marta_Voda [28]

Given:
12 rectangular planks
2 sides per plank
Length = 8 ft
Width = 3 ft

Area of a rectangle = Length * Width.
A = 8ft * 3ft
A = 24 ft²

24 ft² x 2 sides of a plank = 48 ft²
48 ft²/plank * 12 planks = 576 ft² is the total area Alex needs to varnish.

576 ft² ÷ 125 ft² = 4.608 pint or round to 5 pints

5 pints x $3.50/pint = $17.50 Total cost that Alex need to spend to varnish all the wooden planks.
