Q. Find factors of the quadratic expression: 3v2−6v+3(?v+?)(v+?)
Identify Numbers for Factoring: We are given the quadratic expression 3v2−6v+3 and we need to factor it into the form (av+b)(cv+d). First, we look for two numbers that multiply to give the product of the coefficient of v2 (which is 3) and the constant term (which is also 3), and add up to give the coefficient of v (which is −6). The product of the coefficient of v2 and the constant term is 3×3=9. We need two numbers that multiply to 9 and add up to −6. The numbers that satisfy these conditions are (av+b)(cv+d)1 and (av+b)(cv+d)1, since (av+b)(cv+d)3 and (av+b)(cv+d)4.
Factor Out Common Factor: Now we can write the quadratic expression as a product of two binomials using the numbers we found.The factored form will be (av+b)(cv+d), where a, b, c, and d are the numbers we are looking for.Since the original quadratic has a leading coefficient of 3, we can factor out a common factor of 3 from the expression to make it easier to find the binomials.We can write 3v2−6v+3 as 3(v2−2v+1).
Factor Quadratic Expression: Next, we factor the quadratic expression inside the parentheses, v2−2v+1. We already know that the numbers −3 and −3 work for the product and sum, but since we factored out a 3, we need to adjust these numbers. The correct numbers that multiply to 1 (the constant term in the parentheses) and add up to −2 (the coefficient of v in the parentheses) are −1 and −1, since (−1)×(−1)=1 and −30. So, the factored form inside the parentheses is −31 or −32.
Combine Factored Forms: Finally, we combine the factored form inside the parentheses with the common factor we factored out earlier.The factored form of the original quadratic expression 3v2−6v+3 is 3(v−1)2.
