Respuesta :
Answer: X=6
Step-by-step explanation:
x^2-36=0
+36 to both sides
x^2=36
square both sides
x=6
The solution is x= +6, -6.
What is Quadratic equation?
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
The first condition for an equation to be a quadratic equation is the coefficient of x2 is a non-zero term(a ≠ 0). For writing a quadratic equation in standard form, the x2 term is written first, followed by the x term, and finally, the constant term is written.
Roots of a Quadratic Equation
The roots of a quadratic equation are the two values of x, which are obtained by solving the quadratic equation. These roots of the quadratic equation are also called the zeros of the equation.
Given:
x² - 36 =0
x² = 36
x= √36
x= ±6
hence, the solution is x= +6, -6.
