Q. Factor as the product of two binomials.81+18x+x2=
Recognize the structure: Recognize the structure of the expression.The given expression is a quadratic in the form of x2+bx+c. We need to find two numbers that multiply to give ac (where a is the coefficient of x2 and c is the constant term) and add to give b (the coefficient of x).
Identify the coefficients: Identify the coefficients a, b, and c in the expression 81+18x+x2.Here, a=1 (coefficient of x2), b=18 (coefficient of x), and c=81 (constant term).
Find two numbers: Find two numbers that multiply to ac (1×81=81) and add up to b (18).The numbers that satisfy these conditions are 9 and 9, since 9×9=81 and 9+9=18.
Write the expression: Write the expression as the product of two binomials using the numbers found in Step 3.The factored form is (x+9)(x+9) or (x+9)2.
