factor 4x^3-5x^2+64x-80

factor

4 x^{3} - 5 x^{2} + 64 x - 80

(4 x - 5) (x^{2} + 16)

Solution steps

4 x^{3} - 5 x^{2} + 64 x - 80

= (4 x^{3} - 5 x^{2}) + (64 x - 80)

Factor out

x^{2}

from

4 x^{3} - 5 x^{2} : x^{2} (4 x - 5)

Factor out

16

from

64 x - 80 : 16 (4 x - 5)

= x^{2} (4 x - 5) + 16 (4 x - 5)

Factor out common term

4 x - 5

= (4 x - 5) (x^{2} + 16)

5 \times 1 0^{- 4}

\frac{12 a ^{3} b ^{2} c - 18 a ^{4} b ^{5} c ^{2}}{6 a ^{2} b c}

2^{- 0.5}

8 (x - 2)
