What is a positive solution of x squared -36=5x

Mathematics

miv72 [106K]3 years ago
4 0
Answer : 9


Explanation:

{x}^{2}  - 36 = 5x


Subtracting -5x from both sides,

{x}^{2}  - 5x - 36 = 0

Soving this quadratic equation by midterm split method,

{x}^{2}  - 9x + 4x - 36 = 0 \\  \\ x(x  - 9) + 4(x - 9) = 0 \\ (x - 9)(x + 4) = 0


So the roots here will be, +9 and -4.

Since the question is about only the positive value.
Your answer will be 9.
