WebIn mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables. To evaluate the expression when \(x = 5\), we substitute \(5\) for \(x\), and then simplify. It's not being multiplied by anything. WebAlgebraic Expression: A combination of numbers, variables, arithmetic operations, constants, and coefficients is called the algebraic expression ADVERTISEMENT Example: 3x2 + 6x 7 Equivalent Expression: The expressions that are the same to each other but look different are termed equivalent expressions The term \(8xy\) has no like terms in the given expression because no other terms contain the two variables \(xy\). 27 terms. C. Given : VR || DC VA = CA Prove : AVAR = ADAC The terms \(2x, 6x\), and \(40x\) are like terms because they all have \(x\). Use the acronym BEDMAS to recall the order of operation.
