(x+2)³=x³-4​

Answer 1

Answer:

plz mark me brilliant

Step-by-step explanation:

(x+2)3 = x3 - 4 ⇒ x3 + 3(x)2(2) + 3(x)(2)2 + 8 = x3 - 4 ⇒ x3 + 6x2 + 12x + 8 = x3 – 4 ⇒ 6x2 + 12x + 12 = 0 ⇒ x2 + 2x + 2 = 0 Consider b2 – 4ac = 22 – 4(1)(2) = 4 – 8 = –4 Hence the given equation does not have real roots

Answer 2

I am sorry I found the value of x
