SUBTRACT:
(2x² - 5x + 7) from (3x² + 4x - 6 )
ANSWER
x² + 9x - 15
EXPLANATION
when we are subtracting algebraic expressions, we first need to remove the brackets ( we may need to use distributive property ). After that, we need to combine all the like terms to get the irreducible form of the expression.
The second number has a coefficient of -1, So, first we'll multiply each term of the second number with -1.
(3x² + 4x - 6 ) - (2x² - 5x + 7)
(3x² + 4x - 6 ) - 2x² + 5x - 7
3x² + 4x - 6 - 2x² + 5x - 7
Like terms refers to the terms that have same variables and the power of the variable is also same.
Combining like terms
( 3x² - 2x² ) + 4x - 6 + 5x - 7
x² + 4x - 6 + 5x - 7
x² + ( 4x + 5x ) - 6 - 7
x² + 9x - 6 - 7
x² + 9x - 15
