(b 2)2 = (9 2)2 ( b 2) 2 = ( 9 2) 2. x2+9x+20=0 Step 1: Factor left side of equation. factorise using identities. We have, x² - 9x + 3 = 0. The factors of x^2 + 9x + 20 are (x+4) & (x+5). (x−5)(x− 4) ( x - 5) ( x - 4) x ^ 2 +9x +20 = 0. Input. What is a quadratic equation? A quadratic equation is a second-order polynomial equation in a single variable x as: ax² + bx + c = 0. (x - 5) (x + 4) = 0 d report flag outlined. Add 81/4 to both sides of the equation : On the right hand side we have : x= +2i square root 6, x= -2i square root 6. How to Use the Calculator. Then you solve the equations. u2 − 9u+20 = 0 u 2 - 9 u + 20 = 0. Join for free x^2 + 9x + 20 x 5 x 4 (x + 5)(x +4) x = -5,-4 hope this helps Two numbers r and s sum up to -\frac{20}{9} exactly when the average of the two numbers is \frac{1}{2}*-\frac{20}{9} = -\frac{10}{9}. Ask Question. Step 3.333 Step by step solution : Step 1 :Equation at the end of step 1 : ( (22•3x2) - x) - 20 = 0 Algebra. Evaluate. x ^ 2 -9x -20 = 0. x = 0 x = 0. Solution.
