Find the factors of 5x2+20x+20
Akimi4 [234]

Answer:

Step-by-step explanation:

Sum = 20

Product = 5*20 = 100

Factors = 10 , 10   {10*10 = 100 ; 10+10 = 20}

5x² + 20x + 20 = <u>5x² + 10x</u> + <u>10x + 10*2</u>

= 5x(x + 2) + 10(x + 2)

= (x + 2)(5x + 10)

How do i factor the coefficent out of a variable, such as 2.4n+9.6 and -6z+12
ANEK [815]
You are factoring one or more linear expressions (but are not factoring variables).

2.4n+9.6 can be divided by 2.4 and then the result mult. by 2.4:

2.4n+9.6 = 2.4 [ n + 4 ]

Also:  -6z+12= 6 [ -z + 2 ]  Here I have simplified linear functions but factoring out common constant coefficients (not variables).
