Expand the expression and combine like terms. -1/2(-3y+10)

Step-by-step explanation:

The given expression is

We need to find the expanded form of given expression.

According to distributive property, if a,b and c are three real numbers then

Using distributive property, the given expression can be written as

On further simplification we get

Two terms are called like terms if they have same variable of same power.

In the above expression we do not have like terms.

Therefore, the expanded form of given expression is .

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

there is no points to select.
