Forgot how to do polynomials, can someone answer this practice question and explain how you got it 2x^2-3x-5

( x + 1 ) ( 2x - 5 )

Step-by-step explanation:

Break the expression into groups:

2x² - 3x - 5

= ( 2x²+ 2x ) + ( - 5x - 5 )

Factor out  2x  from  :

2x² + 2x  =>  2x ( x + 1 )

Factor out - 5 from :

-5x  - 5 => -5 ( x + 1 )

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

Therefore:

Factor  out common  term : x + 1

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

Hope that helps!

the last choice

step-by-step explanation:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
