Answer 1

Answer: heyyy~

a) a quadratic expression is = 3x²+1=0

What is a Quadratic Equation?

A quadratic equation in math is a second-degree equation of the form ax² + bx + c = 0. Here a, b, are the coefficients, c is the constant term, and x is the variable. Since the variable x is of the second degree, there are two roots or answer for this quadratic equation. The roots of the quadratic equation can be found by either solving by factorizing or through the use of a formula.

b)  a pure quadratic equation is = x²+5=0

What's a pure quadratic equation?

An equation that can be expressed in the form ax2+c=0, where a and c are real numbers and a=0 is a pure quadratic equation. Or the quadratic equation having only second degree variable is called a pure quadratic equation. One example: x2−9=0.

c)  a monic quadratic equation is = 4x²-5x-7

What is A monic quadratic equation?

A monic quadratic equation is a single variable quadratic equation in which the leading coefficient of degree 2 .

d) a quadratic equation is = x²+2x+3=0

What is a quadratic equation?

any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power solve for x in the quadratic equation x2 + 4x + 4 = 0.
