Question

factorizar: a) 25x∧4+ 10x ³-5x²
b) 8x³-5x²
c) 12x³+6x²-3x
d) 3y³+6y² -12y+ 9
e)5a∧4-10a+ 15a³+20a²
f) 10x³+15x²

Answer 1

a)=$25x^2x^2+10x x^2-5x^2$

$=5\cdot \:5x^2x^2+5\cdot \:2xx^2-5x^2$

$=5x^2\left(5x^2+2x-1\right)$

b) =$x^{2} (8x-5)$

c)$=12x^2x+6xx-3x$

$=3\cdot \:4x^2x+3\cdot \:2xx-3x$

$=3x\left(4x^2+2x-1\right)$

d)$=3y^3+3\cdot \:2y^2-3\cdot \:4y+3\cdot \:3$

$=3\left(y^3+2y^2-4y+3\right)$

e)$=5a^3a+15a^2a+20aa-10a$

$=5a^3a+5\cdot \:3a^2a+5\cdot \:4aa-5\cdot \:2a$

$=5a\left(a^3+3a^2+4a-2\right)$

f)$=10x x^2+15x^2$

$=5\cdot \:2xx^2+5\cdot \:3x^2$

$=5x^2\left(2x+3\right)$

intente hacerlo lo mas simple y comprensible
