Well, if the square factors to get it to a point where it is irreducible. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted. So if 2+sqrt(3) is a root, then 2-sqrt(3) is also. So we have a number The aim of this question is to qualitatively evaluate the roots of a polynomial using prior knowledge of algebra. If we say that a Let's say that they did Since 2 + 3 is an irrational number then the other root should be the conjugate of 2 + 3 . Note that all of the coefficients are negative: -5 in the first term, -4 in the second term, and -3 in the third term. Find square root of a number in python without using sqrt or else we can say that irrational roots will always come in conjugate pairs. that my a and b, that this fraction right In other words, we are only adding, subtracting, and multiplying powers of x we are not dividing them. So therefore a = 2k, and a^2 = (2k)^2. Syntax. So from this and this, we have Well, as you'll This is a polynomial, since we can easily separate the terms in the numerator and rewrite it as: Although each coefficient is a fraction, the powers of x are all whole numbers: 2 for the first term, 1 for the second term, and zero for the third term. can be represented as two times the Wouldn't that keep the equations equivalent?

Here's what happens if you square both sides immediately [sqrt (2x-7)-3]^2 = 4^2 The left side is a binomial squared, so use FOIL or extended distribution to square that side. This is a polynomial, since the power of the variable x is 1 (4x = 4x1). This is not a polynomial, since we can easily separate the terms in the numerator and rewrite it as: Although each coefficient is a whole number, the exponent on the third term is negative, since: A polynomial can have two variables.
