Question

20x²-20x+5 (Factorise the following)​

Answer 1

The Question Seems Wrong Either the Coefficient of x should be 21 or 15. And If Its right Please Mention a Method to solve it.

like Quadratic Formula.?

Answer 2

${\tt{\purple{\underline{\underline{\huge{Answer♡}}}}}}$

20x² - 20x + 5 = 0

20x² - 10x - 10x + 5 = 0

10x (2x - 1) - 5 (2x - 1) = 0

(10x - 5) = 0 or (2x - 1) = 0

10x = 5 or 2x = 1

x =$\cancel\dfrac{5}{10}$ or x =$\dfrac{1}{2}$

x =$\dfrac{1}{2}$ or x =$\dfrac{1}{2}$
