Answer:
In mathematics, there are some properties of numbers that are handy to know. For example, the identity property of multiplication says that any number times one is equal to the original number. So, according to that property 5 x 1 = 5.
Step-by-step explanation:
Answer:
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You need to apply the Distributive property on the left member of the equation:
2. Now, you must solve for , as following:
Answer:
x=2 is not a solution
Step-by-step explanation:
x^4 +2x^3 -x^2 -2x = 0
I will factor by grouping
x^4 -x^2 + 2x^3 -2x =0
Factor out x^2 from the first group and 2x from the second group
x^2(x^2-1) +2x(x^2-1) =0
Now factor out x^2-1
(x^2-1) (x^2+2x)=0
From the second term we can factor out an x
(x^2-1) x(x+2)=0
Using the zero product property
(x^2-1) =0 x = 0 (x+2)=0
x^2 =1 x=0 x=-2
Taking the square root
x=±1 x=0 x= -2
The solutions are -2,-1,0,1
Step-by-step explanation:
Given
if x = 5 Then
(x+ 3)²
= ( 5 + 3) ²
= 8²
= 64
Hope it will help :)❤
