How do you solve quadratics using the principal square root function?

∙ 8y ago
The first step is to write the quadratic in the form ax^2 + bx + c = 0 where x is the variable and a, b and c are constants.
Then the two solutions are
[- b - sqrt(b^2 - 4ac)]/(2a) and [- b + sqrt(b^2 - 4ac)]/(2a)

∙ 8y agoThe details vary, depending on the "quadratic" you want to solve. For some equations, you can take the square root on both sides. Please note that doing this, some of the solutions can disappear in the modified equation (i.e., after taking the square root).

What are the rules of quadratics?
1. Quadratics should always contain a set of numbers inconjuction with letters (x usually). 2. Quadratics are always in the form ax2 + bx + c. Where a,b and c are constants and x is a variable. 'a' must always equal '0'. 3. The total equation must never equal '0'. 4. To solve quadratics, you DO NOT factorise. 5. To solve quadratics, use the formula x=a, therefore, b=c. 6. The word 'quadratics' literally means four. This in term means that there are four ways you can solve for the answer of the equation.
Is pi used to solve square root?
No, pi is not used to solve a square root problem.
What is the inverse of the square root of 3x minus 7?
to find the inverse of a function you switch the x and y values, then solve for y. so y=(3x-7)^1/2 would change into x=(3y-7)^1/2. then you would square both sides to get rid of the square root and solve for y

What is completing the square used for?
Completing the square is a method used to solve a quadratic function. This is a handy method when there are two instances of the same variable in the function.
Where was the polynomial originated?
The Babylonians solve quadratics in radicals about 2500 B.C.E. It was Euclid, ca. 300 B.C.E. who demonstrates a geometrical construction for solving a quadratic. however, he does not solve it.
What nineteenth century French mathematician worked with quadratic formulas?
Evariste Galois worked on quadratics when he was a teenager. He was able to establish the means to solve quadratics using radicals and laid the ground work for what became Galois theory. Unfortunately, he died when he was only 20 years old during a duel.
How can you use functions to solve real-world problems?
The basic idea is to represent the relationship between two variables as a function. Many problems in physics, chemistry, etc. use common functions (such as the square function, the square root function, the exponential function), or more complicated functions.
How do you solve an economic function?
It really depends on the specific function, and what you want to solve for.
Can all quadratics be solved by completing the square?
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by factoring, using the square roots or quadratic formula. Solving quadratic equations by completing the square will always work when solving quadratic equations-You can also use division or even simply take a GCF, set the quantities( ) equal to zero, and subtract or add to solve for the variable
Is pi used to solve square root?
No, pi is not used to solve a square root problem.

How are quadratic equations used in real life?
Many real life physics problems are parabolic in nature. Parabolas can be shown as a quadratic equation. If you have two variables then usually you can use the equation to find the best solution to a problem. Also, it is a beginning in the world of mathematical optimization. Some equations use more than two variables and require the technique used to solve quadratics to solve them. I just ran an optimization of 128 variables. To understand the parameters I needed to set I had to understand quadratics.
Who invented square numbers?
According to Askville... "The ancient Babylonians routinely manipulated squares and square roots (see below) The term square is as old as the oldest written record. The ancient Babylonians routinely manipulated squares and square roots. Babylonian mathematics was, in many ways, more advanced than Egyptian maths. They could extract square and cube roots, work with Pythagorean triples 1200 years before Pythagoras, had a knowledge of pi and possibly e (the exponential function), could solve some quadratics and even polynomials of degree 8, solved linear equations and could also deal with circular measurement. Babylonian mathematics was based much more on algebra and less on geometry, in contrast to the Greeks."
