How do you factor p2-6p-18?
You have to use the quadratic formula: p=(6±√(36+72))/2 p=(6±√108)/2 p=3±3√3
How do you factor W2-8W-28?
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 4 plus or minus 2 times the square root of 11x = 10.6332495807108x = -2.6332495807108
How do you factor x2-6x plus 1?
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: 3 plus or minus 2 times the square root of 2x = 5.82842712474619x = 0.1715728752538097
How do you factor x2-2x-11?
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 1 plus or minus 2 times the square root of 3 x = 4.464101615137754 x = -2.464101615137754
How do you factor x2 plus 4x - 8?
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: -2 plus or minus 2 times the square root of 3x = 1.4641x = -5.4641
What is the quadratic equation used for?
It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.
Can Quadratic equations that can be solved using the quadratic formula also be solved by factoring?
Yes, however not all quadratic equations can easily be solved by factoring, sometimes you can factor and sometimes it is easier to use the quadratic formula. Example: x2 + 4x + 4 This can be easily factored to (x + 2)(x +2) Therefore the answer is -2 by setting x +2 = 0 and solving for x This can be done using the quadratic equation and you would get the same results, however, it was much faster to factor instead.
What is the factor quadratic of 18x2 plus 15x plus 2?
18x2 + 15x + 2 = (3x + 2)(6x + 1)
How do you factor -5b2 plus 7b-2?
It is: (-5b+2)(b-1) with the help of the quadratic equation formula

How do you solve a quadratic equation that will not factor?
How you solve an equation that doesn't factor is to plug a quadratic equation's format; ax2+bx+c into the quadratic formula which is x=-b+square root to (b2-4ac)/2a.
What is the quadratic trinomials factor of 12xsquared-20x -8?
12x2-20x-8 = (12x+4)(x-2)
How do you solve 4x2 - 4x plus 2 equals 0?
If you can't factor it easily, use the quadratic formula.
What method(s) would you choose to solve the quadratic equation -2x2 8x 130?
I'd substitute the values -2, 8 and 130 into the quadratic formula and wind up with two real solutions: 2 plus or minus -1 times the square root of 69 x = -6.306623862918075 x = 10.306623862918075
How do you solve Quadratic functions?
All you do is set the quadratic function to equal to 0. Then you can either factor or use the quadratic formula to solve for your unknown variable.
How do you compute the intercepts of a quadratic function?
Use the quadratic equation. If ax+bx+c=0 x=(-b±(b^2-4ac)^(1/2))/2a. You could also complete the square, factor,or graph the equation.
What is the factor of 2x2-10x plus 3?
Doesn't factor evenly, use quadratic
