To settle the equation, factor x^2-6x-55 using formula x^2+left(a+b ight)x+ab=left(x+a ight)left(x+b ight). To uncover a and also b, collection up a device to be solved.

You are watching: Factor x^2-6x


Since ab is negative, a and b have the opposite signs. Because a+b is negative, the an unfavorable number has greater absolute value than the positive. List all such integer bag that give product -55.

To fix the equation, element x^2-6x-55 utilizing formula x^2+left(a+b ight)x+ab=left(x+a ight)left(x+b ight). To find a and also b, collection up a device to be solved.
Since ab is negative, a and b have the opposite signs. Because a+b is negative, the negative number has better absolute worth than the positive. List all together integer pairs that give product -55.
To settle the equation, variable the left hand next by grouping. First, left hand side needs to be rewritten as x^2+ax+bx-55. To uncover a and b, set up a mechanism to it is in solved.
Since abdominal is negative, a and b have actually the the contrary signs. Due to the fact that a+b is negative, the negative number has better absolute worth than the positive. List all such integer pairs that provide product -55.
All equations of the type ax^2+bx+c=0 have the right to be fixed using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula offers two solutions, one as soon as ± is addition and one as soon as it is subtraction.
This equation is in traditional form: ax^2+bx+c=0. Substitute 1 for a, -6 for b, and also -55 because that c in the quadratic formula, frac-b±sqrtb^2-4ac2a.
Quadratic equations such as this one can be solved by perfect the square. In stimulate to complete the square, the equation must an initial be in the type x^2+bx=c.
Divide -6, the coefficient the the x term, through 2 to acquire -3. Then add the square the -3 to both sides of the equation. This step makes the left hand next of the equation a perfect square.
