Q. Factor as the product of two binomials.36+12x+x2=
Recognize the structure: Recognize the structure of the expression.The given expression is a quadratic trinomial, which can often be factored into the product of two binomials.36+12x+x2 can be written as (ax+b)(cx+d), where a, b, c, and d are numbers we need to find.
Look for a pattern: Look for a pattern in the coefficients.The expression is in the form of x2+bx+c, where b is the coefficient of x and c is the constant term.In this case, b=12 and c=36.We need to find two numbers that multiply to give c (36) and add up to give b (12).
Find the two numbers: Find the two numbers that fit the pattern.The numbers that multiply to 36 and add up to 12 are 6 and 6, since 6×6=36 and 6+6=12.
Write the expression: Write the expression as the product of two binomials.Using the numbers found in Step 3, we can write the expression as (x+6)(x+6).
Check the factored form: Check the factored form by expanding it.(x+6)(x+6)=x2+6x+6x+36=x2+12x+36This matches the original expression, so the factoring is correct.
