How do you solve 16x2 - 24x plus 7 equals 0?
If you can't factor it easily, use the quadratic formula.
Factor x squared plus x minus 10?
to factor this equation you need to use the quadratic formula:in this question a=1, b=1, c= -10so after you plug in those number you answer would be:x= (-1+ or - the square root of -39) divided by 2
I need An answer for 2x square -3x-2 0?
there is no problem with this quadratic equation it's 2x square - 3x -2 = 0 I need an answer. where it says square there should be a little 2 at the top corner of the 2x to make it 2x square thanks If you can't factor it easily then use the quadratic equation: The two solutions are: 2 & -.5
What is the derivative of x divided by 2?
x/2 is the same as (1/2) times x. Thus, you can use the formula for a constant factor.
How do you solve m squared minus 8m equals zero?
m2 - 8m = 0Factor the expression on the left:m (m - 8) = 0If either factor is zero, then the two sides are equal:m - 8 = 0m = 8m = 0
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 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.
In mathematics how does one use the quadratic formula?
The Quadratic formula in mathematics is used to solve quadratic equations in algebra. The simplest way to solve these equations is to set each of the factors to zero and then solve each factor separately.
Find a possible formula for the quadratic function whose graph has x intercepts 4 and 8 and y intercept 26?
The x-intercepts are quite easy. Just write the equation: y = (x - 4)(x - 8) To get the desired y-intercept, you need to multiply this by a scale factor (a constant). Just calculate the y-intercept for the equation as shown above; that will show you by what constant you need to multiply (for example, if the y-intercept is 13, add a factor of 2, to get 26).
How do you Factor this 21x2-13x-20 into a Quadratic formula?
(3x - 4)(7x + 5)
How do you factor x2 plus 7x minus 6?
This is not factorable. You would have to do the quadratic formula for this problem.
What is the answer to 2xsquared plus 18x-14?
By using the quadratic formula the given quadratic expression will factor into irrational numbers and so therefore a straight forward answer is quite difficult.
What are the three ways to solve quadratic equations?
1) Put everything on the left side, and factor.2) Complete a perfect square on the left side.3) Use the quadratic formula. If ax2 + bx + c = 0, then x = (-b plusminus squareroot(b2 - 4ac)) / 2a.
What do you use the quadratic formula for?
One would use the quadratic formula for solving binomials that are otherwise hard to factor. You can find both real and imaginary solutions using this method, making it highly superior to factoring in this regard.
How To Factor Trinomials?
Find one factor by substituting in values, then use long division. You can then apply the quadratic formula to the result - or factorise it by sight, of course
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 16x2 - 24x plus 7 equals 0?
If you can't factor it easily, use the quadratic formula.
