Substitute the values a = 1 a = 1, b = −8 b = - 8, and c = −5 c = - 5 into the quadratic formula and solve for x x. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. 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. A quadratic equation has at most two solutions. Use the quadratic formula to find the solutions. Add 4 4 to both sides of the equation.
Algebra. Get help on the web or with our math app. Now the clever bit: Take the coefficient of x , which is 8 , divide by two, giving 4 , and finally square it giving 16. Convert the inequality to an equation.

Solve Using the Quadratic Formula x^2-8x+15=0. If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0.500 Step by step solution : Step 1 :Equation at the end of step 1 : (22x2 + 8x) - 5 = 0 Step 2 :Trying to factor by -9x2+8x-5=0 Two solutions were found : x = (-8-√-116)/-18= (4+i√ 29 )/9= 0. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. To use the direct factoring method, the equation must be in the form x^2+Bx+C=0. To do this we work with the coefficient of x, not x 2. 8±√(−8)2 −4 ⋅(1⋅−5) 2⋅1 8
x2 + 8x + 15 ≥ 0 x 2 + 8 x + 15 ≥ 0. If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0.
