Factor completely 2x3 + 8x2 + 3x + 12.
(2x2 + 3)(x + 4)
(2x2 + 3)(x − 4)
(2x2 − 3)(x + 4)
(2x2 − 3)(x − 4)

.

Step-by-step explanation:

We need to find the factors of given equation;

Solution:

On Solving the above equation we get;

Now First we will take common factor from first 2 terms which is we get;

Now we will take the common factor from the last 2 terms which is 3 we get;

Here we get 2 terms in which is common factor.

Hence After factorizing the given equation we get .

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
