factor 28y^2-21y

Solution

factor

28 y^{2} - 21 y

Solution

7 y (4 y - 3)

Solution steps

28 y^{2} - 21 y

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

y^{2} = yy

= 28 yy - 21 y

Rewrite

28

as

7 \cdot 4

Rewrite

21

as

7 \cdot 3

= 7 \cdot 4 yy - 7 \cdot 3 y

Factor out common term

7 y

= 7 y (4 y - 3)
