Q. Which of the following is equivalent to (x3+2)(23x) ?Choose 1 answer:(A) 49(B) 93x+2(C) 49x2(D) 6+4x3x2
Simplify denominator of complex fraction: Simplify the denominator of the complex fraction.The denominator is (x3)+2. To combine these terms, we need a common denominator, which is x. So we rewrite the terms with a common denominator:(x3)+2=(x3)+(x2x)
Combine terms in denominator: Combine the terms in the denominator.Now that we have a common denominator, we can combine the terms:(x3)+(x2x)=x3+2x
Rewrite complex fraction as division: Rewrite the complex fraction as a division.The original expression x3+223x can now be written as:23x÷x3+2x
Divide by fraction by multiplying by reciprocal: Divide by a fraction by multiplying by its reciprocal.To divide by a fraction, we multiply by its reciprocal. The reciprocal of (x3+2x) is (3+2xx):(23x)⋅(3+2xx)
Simplify expression: Simplify the expression.Now we multiply the numerators and the denominators:(3x×x)/(2×(3+2x))This simplifies to:(3x2)/(6+4x)
