Explanation Given information: The equation, x 4 − x 2 = 6 . 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. Zero product property, If a product of two number is zero, one of the two must be zero. Calculation: Consider the expression, x 4 − x 2 = 6 Rewrite the expression as, x 4 − x 2 − 6 = 0 The left side expression is x 4 − x 2 − 6 . The above expression can be written as, ( x 2 ) 2 − x 2 − 6 Substitute x 2 = y in the above expression, y 2 − y − 6 Factor of y 2 are ( y ) ( y ) . The factors of − 6 are ( 1 ) ( − 6 ) , ( 2 ) ( − 3 ) , ( − 2 ) ( 3 ) and ( − 1 ) ( 6 ) . Consider the factors ( y ) ( y ) and ( 1 ) ( − 6 ) . Now, ( y + 1 ) ( y − 6 ) = y ( y − 6 ) + 1 ( y − 6 ) = y 2 − 6 y + y − 6 = y 2 − 5 y − 6 Which is not the original expression
