Question

Factorise:x³+x²-4x-4​

Answer 1

Step-by-step explanation:

${x}^{3} + {x}^{2} - 4x - 4 \\ {x}^{2} (x - 1) - 4(x - 1) \\ (x - 1)( {x}^{2} - 4)$

please mark me as the brainliest

Answer 2

first take common in x^3+x^2 =x^2(x+1)

then take second common in -4x-4 = -4(x+1)

now,

combine it.....x^2(x+1)-4(x+1)

since, x+1 is common

the required ans is

(x+1) (x^2-4)
