(x + 5) (x + 1) = 0x2 + 6x + 5 = 0
If the value under the radical sign (the discriminant) in the quadratic formula is negative, it means that the quadratic equation has no real solutions. Instead, it has two complex (or imaginary) solutions. This occurs because the square root of a negative number is not defined in the set of real numbers, indicating that the parabola represented by the equation does not intersect the x-axis.
Putting a negative number in parentheses merely assists a subtraction sum involving negative numbers. For example, 14 - (-17) = 31.
Two numbers are negative reciprocals if their product is -1. The numbers 1/2 and -2 are negative reciprocals. Their product is -1. This is often seen in problems involving the slopes of two lines. The slopes of perpendicular lines are negative reciprocals. Their product is -1.
Polynomials and nonpolynomial expressions both represent mathematical functions and can be used to model relationships between variables. They share the property of being defined over real or complex numbers, and both can appear in equations and inequalities. However, polynomials consist solely of non-negative integer exponents on their variables, while nonpolynomials may include variables raised to fractional or negative exponents, transcendental functions, or other forms that do not fit the polynomial criteria.
The numbers can have a positive or negative sign.
imaginary numbers occur in the quadratic formula because of the radical symbol, and the possibility of a negative radican and that results in imaginary numbers. I hope this helped!
calculate long polynomials to high precision by the "method of differences", a technique resembling numerical integration but just involving enormous numbers of additions.
yes . .its all polynomials numbers only would be written in signed nos. .

Yes, it cannot contain any imaginary numbers
no

There is no specific term for such polynomials. They may be referred to as are polynomials with only purely complex roots.
