The two expressions that make a solution of 19 will be x - 9 and (x - 9)².
What is Algebra?
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be two.
Let the solution of the x be 9.
Then the linear equation whose solution is 9 will be
x = 9
x - 9 = 0
The quadratic equation whose solution is 9 will be
x = 9
x - 9 = 0
(x - 9)² = 0
The two expressions that make a solution of 19 will be x - 9 and (x - 9)².
