alright samething but need help simplifyin the expression(the other 2 is 4 squared) 2x2+4x2-(x-3)-3x
I assume you mean
3x2 + 4x2 - (x-3) - 3x
= 6x2 - x + 3 - 3x
= 6x2 - 4x + 3
obviously that first term should have been
2x2
To simplify the expression 2x^2 + 4x^2 - (x - 3) - 3x, we can follow these steps:
Step 1: Combine like terms within parentheses
Inside the parentheses, we have (x - 3). To simplify, we distribute the negative sign, so it becomes -x + 3.
Step 2: Remove the parentheses
Now the expression becomes 2x^2 + 4x^2 - x + 3 - 3x.
Step 3: Combine like terms
Next, we group the like terms together. The like terms in this expression are the ones with the same variable and exponent.
So, we have (2x^2 + 4x^2) - x - 3x + 3.
Step 4: Add or subtract coefficients
Within each set of like terms, we can either add or subtract their coefficients. For example, 2x^2 + 4x^2 equals 6x^2.
The simplified expression then becomes:
6x^2 - x - 3x + 3.
Now let's simplify it further.
Step 5: Combine like terms again
Now we can combine the like terms with the same variables. So, we have 6x^2 - x - 3x + 3.
Step 6: Add or subtract coefficients
We add or subtract the coefficients of the like terms. -x and -3x can be combined to give -4x.
The simplified expression is:
6x^2 - 4x + 3.
Therefore, the simplified expression for 2x^2 + 4x^2 - (x - 3) - 3x is 6x^2 - 4x + 3.
