Question

Factorize 16y² - 4y for me plz ... Hint... It's not [4y( 4y -1) ]
Tq.

Answer 1

Answer:

Step-by-step explanation:

16y^2 - 4y

$(4y)^2-(2\sqrt{y} )^2$

then by the basic identity

that is

$a^2-b^2=(a+b)(a-b)$

we get this expression factorized as

$(4y+2\sqrt{y} )(4y-2\sqrt{y} )$

this expression can be factorized as above

i hope you understand the solution
