Name: Key Date: FUN 1 - N1 Today, you will be able to: Translate an algebraic expression ALGEBRAIC EXPRESSION - uses one or more variables & constants, but does not contain a relation symbol KEY WORDS TO WATCH FOR WHEN TRANSLATING: | | ADD | SUBTRACT | MULTIPLY | DIVIDE | |---|---|---|---| | | sum | difference | product | quotient | | | more than | less than | of | | | | increased by | decreased by | double | | | | exceeds | fewer than | twice | | | | | reduced by | triple | | *** Be careful when using LESS THAN, FEWER THAN, SUBTRACTED FROM - they reverse the order!!!*** Write an algebraic expression for each: the sum of x and 7 x + 7 the product of g and 10 10g r decreased by 2 r - 2 3 less than w w - 3 the product of 5r and s 5rs twice x, decreased by 10: 2x - 10 m exceeded by 5: m + 5 12 increased by the square of q: q² + 12 r more than w: r + w 3 fewer than 6 times n: 6n - 3 5 more than 3 times y: 3y + 5 4 less than the square of n: n² - 4 one-third of c: ⅓c 13 subtracted from half of r: ½r - 13 *** When multiplying by a quantity (like a sum or difference), you must use ( )!!! *** three times the sum of p and q: 3(p + q) twice the quantity x plus y: 2(x + y) one-fourth the quantity 16 less than n: ¼(n - 16) (a - 3)(a + 7) a(a + 7) - 3(a + 7) a² + 7a - 3a - 21 a² + 4a - 21 (y + 6)(y - 2) y(y - 2) + 6(y - 2) y² - 2y + 6y - 12 y² + 4y - 12 (x + 3)(x - 3) x(x - 3) + 3(x - 3) x² - 3x + 3x - 9 x² - 9 Name: Key Date: FUN 1 - N6 Today, you will be able to: Multiply polynomials (x - 7)(x + 2) x(x + 2) - 7(x + 2) x² + 2x - 7x - 14 x² - 5x - 14 (y + 7)(y - 7) y(y - 7) + 7(y - 7) y² - 7y + 7y - 49 y² - 49 (2x + 1)(x - 6) 2x(x - 6) + 1(x - 6) 2x² - 12x + x - 6 2x² - 11x - 6 (c - 5)(2c - 4) c(2c - 4) - 5(2c - 4) 2c² - 4c - 10c + 20 2c² - 14c + 20
