WebA polynomial cannot have a square root. The reason is that this would involve a power that is not a whole number (since a square root is a power of 1/2). Example 1: Not A Polynomial Due To A Square Root In One Term Consider the expression: 2x + √x – 5 This is not a polynomial, since we have a square root in the second term. WebOct 6, 2024 · Extracting Square Roots. Recall that a quadratic equation is in standard form if it is equal to 0: \[a x^{2}+b x+c=0\] where a, b, and c are real numbers and \(a\neq 0\). A solution to such an equation is called a root.Quadratic equations can have two real solutions, one real solution, or no real solution.

Can linear equations have square roots

WebThe square root operation gives us only the principal square root, or positive positive square root. For example, \sqrt {4}=2 4 = 2, not both -2 −2 and 2 2 even though (-2)^2=2^2=4 (−2)2 = 22 = 4. If a solution leads to equating the square root of a number to a negative number, then that solution is extraneous.
