How do you solve quadratic?
First you factorise it. Then you cancel out the common terms.
15Y2 plus 26y plus 8 greatest common factor?
using the quadratic formula -4/3 and -0.4
15y2 plus 26y plus 8 what common factors of 15 and 8 get 26?
using the quadratic formula -4/3 and -0.4
What do all graphs of quadratic functions have in common?
The graph of a quadratic equation is a parabola.
What does linear and quadratic functions have in common?
Type your answer here... yes linear and quadratic functions have some things in common such as letters and way of solution ;it is my answer
Why quadratic equation is called quadratic?
In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is Where x represents a variable, and a, b, and c, constants, with a ≠ 0. (If a = 0, the equation becomes a linear equation.) The constants a, b, and c, are called respectively, the quadratic coefficient, the linear coefficient and the constant term or free term. The term "quadratic" comes from quadratus, which is the Latin word for "square." Quadratic equations can be solved by factoring, completing the square, graphing, Newton's method, and using the quadratic formula (given below). One common use of quadratic equations is computing trajectories in projectile motion. Because it is in the form of ax^2+bx+c=0
Why is it important to know how to determine the greatest common factor?
It help factor your answers for the future. Especially when you use factoring, quadratic formula and the like. It's very useful when you reach Freshman Algebra.
Do the two quadratic equations have anything in common?
Yes, invisibility.
What is a common mistake in 10 16 into a decimal?
The answer is 0.625. I don't know what the mistake is.
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
What are some common mathematical relationships encountered in physics?
quadratic, inverse, linear
Factorise 6x2-18x equals 12?
First step should be to take everything to the left side:6x2 - 18x - 12 = 0Next you might divide by the common factor, 6:x2 - 3x - 2 = 0It seems you have to use the quadratic formula for this one. Use a = 1, b = -3, c = -2.First step should be to take everything to the left side:6x2 - 18x - 12 = 0Next you might divide by the common factor, 6:x2 - 3x - 2 = 0It seems you have to use the quadratic formula for this one.
