Question

find zeri of polynomial
p(x)=x3+x2-4x-4​

Answer 1

Answer:

${x}^{3} + {x}^{2} - 4x - 4 \\ = {x}^{2} (x + 1) - 4(x + 1) \\ = ( {x}^{2} - 4)(x + 1) \\ {x }^{2} = 4 \: \: | \: \: x = -1\\ x = \sqrt{4} \: \: | \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ x = ±2 \: \: | \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ x = - 2, \: 2, \: - 1 \\ \\ \red{\mathfrak{\underline{\large{Hope \: It \: Helps \: You }}}} \\ \green{\mathfrak{\underline{\large{Mark \: Me \: Brainliest}}}}$
