Question

find the product of using appropriate identities (x+2)(x²-2x+4)​

Answer 1

1. x(x²-2x+4) +2(x²-2x+4)
2. x³-2x²+4x+ 2x²-4x+6
3. x³-2x²+2x²+4x-4x+6
4. x³-0+0+6
5. x³+6

Answer 2

Answer:

$\huge\bigstar\huge\tt\underline\red{ᴀɴsᴡᴇʀ }\bigstar$

Here this identify is used:-

${x}^{3} + {y}^{3} = (x + y)( {x}^{2} + {y}^{2} - xy)$

Here:-

${x}^{3} + {2}^{3} = (x + 2)( {x}^{2} + {2}^{2} - 2x)$

so,answer is x^3 +8

Hope it helps you..!!!
