Mathematics
1 answer:
Oliga [24]3 years ago
5 0
I’d use the app Socratic, the apps always factors the quadratic formula and it gives you the steps on how it done.
1. X^2+7x+12=0
Identify a,b, and c. Which x^2 is a, 7 is b and c is 12.
Find two numbers that multiply together to equal c which is 12 which is 3•4
And add two numbers that equal to b which is 7 which is 3+4
= (x+3)(x+4)=0
Set each factor to zero
X+3=0
= -3
X+4=0
=-4

Write down the fifth term and the general term of<br> following sequence : 8,4,2,...
morpeh [17]

Answer:

The terms listed are 8, 4, and 2 in that order. From what we can see, it is a geometric sequence whose next term is gotten by dividing the previous term by 2. The formula for finding the nth term of a  geometric sequence is given as ar^{n-1}, where

a = first term which is 8

r = common ratio, 1/2 or 0.5

n = is the term we're looking for, 5

Putting all these together into one solid equation, we have

8 * 0.5^{5-1} =

8 * 0.5^{4} =

8 * 0.0625 = 0.5

Therefore, the 5th term of the sequence is 0.5. Similar example can be seen here brainly.com/question/9300199

use the quadratic formula to find both solutions to the quadratic equation given below. check all that apply 5x^2-x-4=0
Setler79 [48]

Answer:

x = -4/5 and x = 1

Step-by-step explanation:

5x^2 - x - 4 = 0

Factor out x from the expression.

x (5x +4) - 5x -4 = 0

Factor out the negative sign from the expression.

x (5x + 4) - (5x+4) = 0

Factor out 5x + 4 from the expression.

(5x +4) x (x-1) = 0

When the product of factors equal 0, that means atleast one factor is 0.

5x+4= 0

x-1 = 0

Solve the equation for x.

5x + 4 = 0

Minus 4 from both sides.

5x = -4

Divide by 5.

x = -4/5

Solve the equation for x.

x - 1 = 0

Add one to both sides.

x = 1

Therefore, x = -4/5 and x = 1.
