FACTORISE
y^2-(a + b) y + ab​

Answer 1

$\mathbb{\huge{\underline{\underline{\red{QUESTION}}}}}$

FACTORISE

y²-(a + b) y + ab

$\mathcal{\huge{\underline{\underline{\green{Answer:-}}}}}$

✒ The factors of y²-(a + b) y + ab is (y−a)(y−b).

$\mathcal{\huge{\underline{\underline{\orange{Solution:-}}}}}$

y² −(a+b)y+ab

=y²−ay−by+ab

=y(y−a)−b(y−a)

=(y−a)(y−b)

Hence, (y−a) and (y−b) are the two

factors for y² −(a+b)y+ab.

Answer 2

$\huge\mathbb\red{Answer}$

y² −(a+b)y+ab

=y²−ay−by+ab

=y(y−a)−b(y−a)

=(y−a)(y−b)

Hence, (y−a) and (y−b) are the two

factors for y² −(a+b)y+ab.
