The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus: x^2 - 36 = 5x x^2 - 5x - 36 = 0 x^2 + 4x - 9x - 36 = 0 x(x + 4) - 9(x + 4) = 0 (x - 9)(x + 4) = 0 x - 9 = 0 or x + 4 = 0 x = 9 or x = -4 Therefore, the positive solution of x^2 - 36 = 5x? is 9.
A quadratic equation is x² - 36 = 5x and the positive value of x is 9.
What is the quadratic equation?
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation. The general form of the quadratic equation is ax² + bx + c.
Given
A quadratic equation is x² - 36 = 5x
How to find the value of x?
A quadratic equation is x² - 36 = 5x that can be represented by
x² - 5x - 36 = 0
By factorisation method
x² - 9x + 4x - 36 = 0
(x - 9)(x + 4) = 0
x = 9 and -4
So the positive value of x is 9.
