x =(2-√24)/-2=1+√ 6 = 1.449
x =(2+√24)/-2=1-√ 6 = -3.449
The expression is simplified to give -7x^2 - 11x
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions that contains variables, constants, factors and coefficients.
They are also made up of arithmetic operations such as addition, subtraction, multiplication, division, etc.
From the information given, we have;
(- x^2 - 5x ) - ( 6x^2 + 5x)
expand the bracket
-x^2 - 5x - 6x^2 - 5x
collect like terms
-7x^2 - 11x
Thus, the expression is simplified to give -7x^2 - 11x
