Factor the expression by grouping. First, the expression demands to be rewritten as -x^2+ax+bx-24. To find a and also b, collection up a mechanism to be solved.
Since abdominal is positive, a and also b have actually the same sign. Since a+b is negative, a and also b room both negative. List all together integer bag that give product 24.
Quadratic polynomial can be factored using the change ax^2+bx+c=aleft(x-x_1 ight)left(x-x_2 ight), whereby x_1 and x_2 space the services of the quadratic equation ax^2+bx+c=0.
x=frac-left(-11 ight)±sqrtleft(-11 ight)^2-4left(-1 ight)left(-24 ight)2left(-1 ight)
All equations the the form ax^2+bx+c=0 deserve to be addressed using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula offers two solutions, one when ± is addition and one as soon as it is subtraction.
