Use the quadratic formal to solve the equation (show all work) (m-4)(3m-10)=3(m-2)+18
The Quadratic Formula The quadratic formula is a fundamental formula used to find the roots of quadratic equations. Roots of quadratic polynomials are defined as the values of the variables for which the quadratic polynomial is equal to zero. For example, given the general form of a quadratic polynomial the roots of the above are defined as the values of x for which the above... read more
Quadratic Equations After learning about multiplying binomials using the FOIL method and discussing polynomials, we can move on to working with quadratic equations. Constructing a Quadratic Equation We discovered that a polynomial is a product of two or more binomials. Let's consider the simple equality If two quantities multiply to get zero, does a = 0 or b = 0? or both... read more
ax^2 +bx + c = 0 Example 7x^2 +12x +16 =0 Don't forget the quadratic formula when you come across a quadratic that CAN'T be factored: x = (-b +/- (sqroot)( b^2 - 4ac))/2a by the way, for those who don't know, I use the ^ sign as my "power" indicator
the problem 7x^2+123x-4
What's the answer
I dont understand how to solve quadratic functions. I'm supposed to solve f(x)-x^2+2x-3 by completing the square but whenever I try to search how to do these kind of problems, I never see...
I'm solving a quadratic equation which is 2x^2-x-10=0 and I know that a=2 b=-1 and c=-10 ans with the problem put it into the formula which is -(-10 +- √ -1^2-4(2)(-10) and when I get my answer...
i have been working on...x^2 +5x +8 =4 for a test review and can't solve the problem. Any help would be great...thx
x2 + 5x + 8 = 4
I'm trying to solve the quadratic formula with these numbers, but my answers always ended up not being whole numbers. Can you solve it for me and tell me what you get?
solve by factoring or using the quadratic formula.
I know how to graph these kinds of equations with parabolas but cannot figure out how to find the factored, vertex, and standard forms of these equations.
use the quadratiic formula
how do you solve?
we are supposed to use the quadratic formula to find.
This method shows how to solve a quadratic equation by using the method of completing the square.
This is my son. Yes he was only 6 when we made this clip. And it's the best testimony I can give of my teaching and tutoring credentials.
In this video, I demonstrate how students can use the Quadratic Formula.
