Basic Of Algebra. Basics of Algebra cover the simple operation of mathematics like addition, subtraction, multiplication, and division involving both constant as well as variables. For example, x+10 = 0. This introduces an important algebraic concept known as equations.
(X-5)2+3(X-5)+9 = 0 let expand the equation (x)x2-(5)x2 + 3(x)-3(5) + 9 = 0 2x-10+3x-15+9=0 collect like terms 2x+3x-10-15+9 =0 5x-10-6 =0 5x-16=0 5x=0+16 5x=16 divide both side by 5 we have x=16/5
