Solve the following equation by factoring. 5x^2 - 9x - 2 = 0 Select the correct choice below and if necessary, fill in the answer box to complete your choice.

Solution

5x^2 -9x-2

Break coefficient of middle term in two terms Sum of middle terms should

be the product of the coefficients of other two terms

5x^2 - 10x +x -2 =0

5x( x-2) +1( x-2) =0

(5x +1)(x-2) =0

x= -1/5 , 2
