Question

2x²-15x+25= Find the roots of x

Answer 1

Hi there!

Given Eqn. :-
2x² - 15x + 25 = 0

by Splitting Middle term :-

2x² - 10x - 5x + 25 = 0

2x (x - 5) - 5 (x - 5) = 0

(x - 5) (2x - 5) = 0

∴ x = 5 n' x = 5 / 2

Hence, The required solution is :-
x = 5 and x = 5 / 2

Hope it helps! :)

Answer 2

Solution:-

given by:-

$2 {x}^{2} - 15x + 25 \\ 2 {x}^{2} - 10x - 5x + 25 \\ 2x(x - 5) - 5(x - 5) \\ (x - 5)(2x - 5) \\ x = 5 \\ x = \frac{5}{2}$
