How to solve :x2+x-20=0 by completing square root method |
|
Answer» Answer: x2-x-20=0 Two solutions were found : x = 5 x = -4 Reformatting the input : Changes made to your input should not affect the solution: (1): "x2" was replaced by "x^2". Step by step solution : Step 1 : Trying to factor by splitting the middle term 1.1 FACTORING x2-x-20 The first term is, x2 its coefficient is 1 . The middle term is, -x its coefficient is -1 . The last term, "the constant", is -20 Step-1 : Multiply the coefficient of the first term by the constant 1 • -20 = -20 Step-2 : Find two factors of -20 whose sum EQUALS the coefficient of the middle term, which is -1 . -20 + 1 = -19 -10 + 2 = -8 -5 + 4 = -1 That's it Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 4 x2 - 5x + 4x - 20 Step-4 : Add up the first 2 terms, PULLING out like factors : x • (x-5) Add up the last 2 terms, pulling out common factors : 4 • (x-5) Step-5 : Add up the FOUR terms of step 4 : (x+4) • (x-5) Which is the desired factorization Equation at the end of step 1 : (x + 4) • (x - 5) = 0 Step 2 : Theory - Roots of a product : 2.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. We shall now solve each term = 0 separately In other words, we are going to solve as many equations as there are terms in the product Any solution of term = 0 SOLVES product = 0 as well. Solving a Single Variable Equation : 2.2 Solve : x+4 = 0 Subtract 4 from both sides of the equation : x = -4 Solving a Single Variable Equation : 2.3 Solve : x-5 = 0 Add 5 to both sides of the equation : x = 5 Supplement : Solving Quadratic Equation Directly Solving x2-x-20 = 0 directly Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula |
