Explanation Given Information: The expression is 10 x 2 − x − 2 . Formula used: To factor binomial of the form of a x 2 + b x + c : 1) Make a list of pairs of factors of a c . 2) Find the pair whose sum is b. Steps to find the factored form of trinomial, x 2 + b x + c Assume that b and c are positive values. Step 1: First of all, look for the monomial factor. Step 2: After that check the type of trinomial. a) For trinomial x 2 + b x + c , use the form: x 2 + b x + c = ( x + ) ( x + ) b) For trinomial x 2 − b x + c , use the form: x 2 − b x + c = ( x − ) ( x − ) c) For trinomial x 2 − b x − c and x 2 + b x − c , use the form: x 2 − b x − c = ( x + ) ( x − )
