X2 3x 18 Answer

Algebra. Factor x^2-3x-18. x2 − 3x − 18 x 2 - 3 x - 18. Consider the form x2 + bx+c x 2 + b x + c. Find a pair of integers whose product is c c and whose sum is b b. In this case, whose product is −18 - 18 and whose sum is −3 - 3. −6,3 - 6, 3. Write the factored form using these integers. (x−6)(x+ 3) ( x - 6) ( x + 3) Popular Problems. Algebra. Solve by Completing the Square x^2+3x-18=0. x2 + 3x − 18 = 0 x 2 + 3 x - 18 = 0. Add 18 18 to both sides of the equation. x2 + 3x = 18 x 2 + 3 x = 18. To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b b. (b 2)2 = (3 2)2 ( b 2) 2 = ( 3 2) 2.

X2 3x 18 AnswerSolve Using the Quadratic Formula x^2-3x-18=0. x2 − 3x − 18 = 0 x 2 - 3 x - 18 = 0. Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. Substitute the values a = 1 a = 1, b = −3 b = - 3, and c = −18 c = - 18 into the quadratic formula and solve for x x. 3x2 3x 18 Two solutions were found x 3 x 2 Rearrange Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

Explanation: Solve for x2 +3x −18 = 0 and the resulting values for x form the reference points for 2 sets of values (domains -> input) Set x2 + 3x −18 = 0. Note that 3 ×6 = 18 and that 6 − 3 = 3 giving: (x +6)(x − 3) = x2 + 3x −18 = 0. So for this condition x = − 6 and x = +3. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ X2 3x 18 0 X 2 3x 18 X 2 4x 5 0e itsizli ini Sa layan Ka Farkl X Tam Say
