WebA "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2. (You can also see this on the graph) We can … WebFeb 6, 2016 · f(x)=x^4+5x^2-36 If f(x) has zeroes at 2 and -2 it will have (x-2)(x+2) as factors. If f(x) has a zero at -3i then (x+3i) will be a factor and we will need to use a fourth factor to "clear" the imaginary component from the coefficients. (Remember we were told the polynomial was of degree 4 and has no imaginary components).
WebFeb 9, 2015 · Taja, First, you only gave 3 roots for a 4th degree polynomial. The missing one is probably imaginary also, (1 +3i). For any root or zero of a polynomial, the relation (x - root) = 0 must hold by definition of a root: where the polynomial crosses zero. So for your set of given zeros, write: (x - 2) = 0. (x + 2) = 0. (x - 1 + 3i) = 0. WebMar 24, 2024 · A root of a polynomial P(z) is a number z_i such that P(z_i)=0. The fundamental theorem of algebra states that a polynomial P(z) of degree n has n roots, …
In algebra, a quartic function is a function of the form $${\displaystyle f(x)=ax^{4}+bx^{3}+cx^{2}+dx+e,}$$where a is nonzero, which is defined by a polynomial of degree four, called a quartic polynomial.
