(a) Explanation Given information: The expression, y 2 + 6 y + 8 . Formula used: Steps to calculate the factors of quadratic equation a x 2 + b x + c by trial and error method, Step1: Factor a x 2 as ( a 1 x ) ( a 2 x ) with a 1 positive. Step2: Factor c as c 1 c 2 . Step 3: Check if a x 2 + b x + c = ( a 1 x ± c 1 ) ( a 2 x ± c 2 ) If yes, then ( a 1 x ± c 1 ) ( a 2 x ± c 2 ) are the factors. Step 4: If not, try other factorization of a x 2 and c and repeat all the steps. The distributive law, ( a ± b ) c = a c ± b c Where, a, b and c are any real numbers. Calculation: Consider the expression, y 2 + 6 y + 8 Factor of y 2 are ( y ) ( y ) and factors of 8 are ( 1 ) ( 8 ) , ( 2 ) ( 4 ) , ( − 2 ) ( − 4 ) and ( − 1 ) ( − 8 ) (b) To determine To calculate: The value of y when the expression y 2 + 6 y + 8 is equal to zero.
