factor 49-168x+144x^2

factor

49 - 168 x + 144 x^{2}

(12 x - 7)^{2}

Solution steps

49 - 168 x + 144 x^{2}

Write in the standard form

= 144 x^{2} - 168 x + 49

Rewrite in the form of

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

144 x^{2} = (12 x)^{2}

49 = 7^{2}

- 168 x = - 2 \cdot 12 x \cdot 7

= (12 x)^{2} - 2 \cdot 12 x \cdot 7 + 7^{2}

Apply Perfect Square Formula:

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

(12 x)^{2} - 2 \cdot 12 x \cdot 7 + 7^{2} = (12 x - 7)^{2}

= (12 x - 7)^{2}

3 \cdot (\frac{1}{2})^{2}

x + 0.2 = - 0.8

2 x^{2} + x - 5 = 0

\frac{12 !}{( 12 - 2 ) ! \cdot 2 !}
