The difference between expression A and B is
x² -9x + 14
what is expression?
A quadratic expression is a second-degree polynomial with the general form ax² + bx + c where a, b and c are constants, and x is the variable.
To subtract expressions, combine like terms by subtracting coefficients. Follow the order of operations and simplify the result.
Given that
A = 7x²-3x+10
B=-4x²+ 6x- 4
To subtract B from A
7x²-3x+10 - (-4x²+ 6x- 4)
open the bracket with -1
7x²-3x+10 + 4x² - 6x + 4
collect like terms
7x² - 6x² -3x - 6x + 10 + 4
simplify
x² -9x + 14
