$\huge\mathrm{Answer:}$

$\mathfrak{Question:-}$

factorize 20z²-16z

$\mathfrak{Given:-}$

The expression is given

$\mathfrak{find:-}$

factors of the expression

$\mathfrak{Solution:-}$

20z² - 16z = 0

by using quadratic formula,

z = −b±(√b²−4ac)

⠀⠀⠀⠀⠀ 2a

=>z = -(-16)+(√16² - 4×20×0).

⠀⠀⠀⠀⠀⠀⠀ 2×20

=>z = 16+ √(256-0)

⠀⠀⠀⠀ ⠀⠀ 40

=>z = 16 + 16

⠀⠀⠀⠀ ⠀⠀ 40

=>z = 32/40.

Hence the root of this expression is 32/40

To make the factors of the expression , the expression must be non zero but here one root comes out to be 0 .

so factors can't be made
