factor 9y^2-48y+64

factor

9 y^{2} - 48 y + 64

(3 y - 8)^{2}

Solution steps

9 y^{2} - 48 y + 64

Rewrite in the form of

a^{2} + 2 ab + b^{2} :

9 y^{2} = (3 y)^{2}

64 = 8^{2}

- 48 y = - 2 \cdot 3 y \cdot 8

= (3 y)^{2} - 2 \cdot 3 y \cdot 8 + 8^{2}

Apply Perfect Square Formula:

a^{2} - 2 ab + b^{2} = (a - b)^{2}

(3 y)^{2} - 2 \cdot 3 y \cdot 8 + 8^{2} = (3 y - 8)^{2}

= (3 y - 8)^{2}

\frac{x ^{3} - 1}{x - 1}

\frac{9 ^{2} - 5 ( 9 ) - 50}{9 - 1}

x - 7 < 14

9 t^{2} + 48 t + 64
