To solve the equation, factor the left hand side by grouping. First, left hand side needs lớn be rewritten as 2x^2+ax+bx-6. Khổng lồ find a and b, mix up a system to lớn be solved.
Since ab is negative, a & b have the opposite signs. Since a+b is negative, the negative number has greater absolute value than the positive. Danh sách all such integer pairs that give sản phẩm -12.
All equations of the size ax^2+bx+c=0 can be solved using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula gives two solutions, one when ± is addition và one when it is subtraction.
This equation is in standard form: ax^2+bx+c=0. Substitute 2 for a, -1 for b, and -6 for c in the quadratic formula, frac-b±sqrtb^2-4ac2a.
Quadratic equations such as this one can be solved by completing the square. In order khổng lồ complete the square, the equation must first be in the form x^2+bx=c.
Divide -frac12, the coefficient of the x term, by 2 khổng lồ get -frac14. Then showroom the square of -frac14 to both sides of the equation. This step makes the left hand side of the equation a perfect square.

Factor x^2-frac12x+frac116. In general, when x^2+bx+c is a perfect square, it can always be factored as left(x+fracb2 ight)^2.
Quadratic equations such as this one can be solved by a new direct factoring method that does not require guess work. Lớn use the direct factoring method, the equation must be in the size x^2+Bx+C=0.This is achieved by dividing both sides of the equation by 2
Let r và s be the factors for the quadratic equation such that x^2+Bx+C=(x−r)(x−s) where sum of factors (r+s)=−B & the sản phẩm of factors rs = C
Two numbers r & s sum up khổng lồ frac12 exactly when the average of the two numbers is frac12*frac12 = frac14. You can also see that the midpoint of r and s corresponds lớn the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. The values of r và s are equidistant from the center by an unknown quantity u. Express r and s with respect to variable u.
