Factor completely 3X^2 -25

Dominik [7]

In order to factor a polynomial, you have to find its roots

$x_1,\ x_2,\ldots,x_n$

So that you can factor it as

$p(x)=(x-x_1)(x-x_2)\cdots(x-x_n)$

So, in this case, we're looking for the solutions of

$3x^2-25=0 \iff 3x^2=25 \iff x^2 = \dfrac{25}{3} \iff x=\pm\sqrt{\dfrac{25}{3}}=\pm\dfrac{5}{\sqrt{3}}$

So, the polynomial can be written as

$3x^2-25 = \left(x-\dfrac{5}{\sqrt{3}}\right)\left(x+\dfrac{5}{\sqrt{3}}\right)$

A science fair poster is a rectangle 4 feet long and 3 feet wide. What is the area of the poster in square inches?

a_sh-v [17]

Answer:

Area of the poster is $1728$ square inches.

Step-by-step explanation:

First let's convert feet into inches.

1 feet = 12 inches

Length of the poster in inches:

$4$ feet = $4*12$ inches

= $48$ inches

Width of the poster in inches :

$3$ feet = $3*12$ inches

= $36$ inches

Area of a rectangle = Length * Width

Area of the poster = $48*36$

= $1728$ square inches

x = 14.

Step-by-step explanation:

Knowing (8x+6) is equal to 118.

You need to solve for x.

Subtract 6 from 118 = 112.

112 / 8 = 14.

Therefore x = 14.
