Q. Factor the expression completely.28x3+49xAnswer:
Identify GCF of terms: Identify the greatest common factor (GCF) of the terms in the expression 28x3 and 49x. The GCF of 28 and 49 is 7, and the GCF of x3 and x is x. So, the GCF of the entire expression is 7x.
Factor out GCF: Factor out the GCF from the expression.28x3+49x=7x(4x2+7)
Check for further factoring: Check if the remaining expression inside the parentheses can be factored further.The expression 4x2+7 does not have any common factors and is not a special polynomial (like a difference of squares or a perfect square trinomial), so it cannot be factored further.
Write final factored form: Write the final factored form of the expression.The completely factored form of the expression is 7x(4x2+7).
