What is the factorization of the trino Mila below -x^2 + 2x + 48

Alexxx [7]

Answer:

-(x-8)(x+6)

Step-by-step explanation:

-x^2+2x+48

-(x^2-2x-48)

-(x-8)(x+6)

The trick is to find two numbers that when they multiply, you get the third term, which in this case, is -48. And when you add those two numbers, you get the second term, which is -2 in this case. The two numbers in this case are -8 and 6.

The first 4 terms of a geometric sequence are 2, 6, 18, 54. Part A: Find the common ratio. Remember the common ratio is the numb

ra1l [238]

Answer:

Common ratio is 3

The three terms are 162, 486, 1458

Step-by-step explanation:

Given: The first 4 terms of a sequence are $2,6,18,54$

To find:

A. the common ratio

B. the next 3 values in the geometric sequence

Solution:

Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.

$\frac{6}{2}=3\\\\\frac{18}{6}=3\\\\\frac{54}{18}=3$

So, the common ratio is $3$

The next three values are as follows:

$54(3)=162\\162(3)=486\\486(3)=1458$

Answer:

9x/4= -9

Mutiply by 4 for both sides.

4(9x/4) cross out 4 and 4, divide by 4 and then becomes 9x. (-9)(4)= -36

9x= -36

Divide by 9 for both sides

9x/9= -36/9

x= -4
