Steps Using Direct Factoring Method. x^{2}+8x+15=0. x2 − 8x+(−4)2 = 0+(−4)2 x 2 - 8 x + ( - 4) 2 = 0 + ( - 4) 2. Solve by Factoring x^2-8x+15=0. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. Related Symbolab blog posts. (b 2)2 = (−4)2 ( b 2) 2 = ( - 4) 2. x2 − 8x − 20 = 0 x 2 - 8 x - 20 = 0. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. x2 − 8x = 3 x 2 - 8 x = 3.
2x2+8x-12=0 Two solutions were found : x = (-4-√40)/2=-2-√ 10 = -5.5984i x = (-8+√-116)/-18= (4-i√ 29 )/9= 0. Substitute the values a = 1 a = 1, b = −8 b = - 8, and c = −4 c = - 4 into the quadratic formula and solve for x x. 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. 2x2 − 8x = 0 2 x 2 - 8 x = 0. (b 2)2 = (4)2 ( b 2) 2 = ( 4) 2. To use the direct factoring method, the equation must be in the form x^2+Bx+C=0.
An example of a polynomial of a single indeterminate x is x² − 4x + 7.

First problem: x2 + -8 x = 9. Tap for more steps (x−5)(x− 3) = 0 ( x - 5) ( x - 3) = 0. To use the direct factoring method, the equation must be in the form x^2+Bx+C=0. x = 4 +- 3sqrt2 I'm assuming we need to also solve the equation. Now the clever bit: Take the coefficient of x , which is 8 , divide by two, giving 4 , and finally square it giving 16. b2 − 4(ac) b 2 - 4 ( a c) Substitute in the values of a a, b b, and c c. Get help on the web or with our math app. Solve for x. 1: 2: 3: 4: 5: 6: 7: 8: 9: 0. Solve by Completing the Square x^2-8x+7=0. Enter a problem Cooking Calculators. x−5 = 0 x - 5 = 0
