How do you factor out the trinomial: 6x²+14x+4

Answers

6x² + 14x + 4
sum: 14 (12+2=14)
product: (6 × 4 = 24) (12×2=24)

6x² + 12x + 2x + 4
6x(x + 2) + 2(x + 2)
(6x + 2)(x + 2)

Reese read twice as many pages Saturday than she read Sunday. If she read a total of 78 pages over the weekend, how many pages did Reese read Sunday?

Answers

Given:

Reese read twice as many pages Saturday than she read Sunday.

She read a total of 78 pages over the weekend.

To find:

The number of pages she read on Sunday.

Solution:

Let x be the number of pages she read on Sunday.

Reese read twice as many pages Saturday than she read Sunday. So, the number of pager she read on Saturday is 2x.

Total number of page she read over the weekend is:

$Total=x+2x$

$Total=3x$

She read a total of 78 pages over the weekend.

$3x=78$

$x=(78)/(3)$

$x=26$

Therefore, Reese read 26 pages on Sunday.

Write a linear factorization of the function.

f(x) = x^4 + 64x^2

Answers

we are given with the function f(x) = x^4 + 64x^2 and is asked to factor the function. The greatest common factor of the terms is x^2 . hence taking out x^2 from the set, the result is x2 *(x2 + 64).(x2 + 64) is equal to (x+8)^2 - 16x. hence the linear factorization is x^2 * ( (x+8)^2 - 16x)

Hello,

y=x^4+64x&
In IR, y=x^2(x^2+64).

In C, y=x²(x+8i)(x-8i)
