It is useful for simplifying algebraic expressions, for solving certain types of equations, and for numerical work. When we write JC2 + 5x + 6 = (x + 2)(x + 3), 10. Factoring we are factoring the left-hand side. If a given polynomial has integer coefficients, we generally look for factors with integer coefficients. A familiar kind of factoring is removing a common polynomial factor. Examples: x4 (3x - _ 6χ3 _ Ίχ2 = χ 2( χ 2 1)(JC2 + 4) + 2(3* - _ 6 χ _ 7)? 1)(4JC + 5) + (Sx - l) 2 = (3JC - l)[(x2 + 4) + 2(4* + 5) + (3* - 1)] = ( 3 J C - l)(x2 + 11JC+ 13).

Rules for square roots Let a and b be positive real numbers. Then (2) Va^ = a, (1) {Va? = a, (3) Väb - Vä Vb, Vb Vb Rules (1) and (2) come directly from the definition of square roots. To check rule (3), let Vä = r and y/b = s. Then a = r2 and b = s2, hence ab = r2s2 = (rs)2. This says that ^fäb = rs = \fa Λ/Ϊ>. Rule (4) is checked similarly. Warning: These rules concern only multiplication and division. Square roots have no simple behavior with respect to addition and subtraction. In particular, VâT~b IS NOT Va+ Vbl For example, \/25 = \/9 + 16 and V25 = 5, but 5 φ y/9 + VÏ6 = 3 + 4 = 7.
