lana uses factoring by grouping to factor the polynomial 8x2y−10xy2+12x−15y. her work is shown below, but the last two lines of work are missing.

8x2y−10xy2+12x−15y

(8x2y−10xy2)+(12x−15y)

__[blank 1]__

__[blank 2]__

select one statement for each blank to correctly complete lana’s work.

blank 1: 2xy(4x−5y)+3(4x−5y)

blank 1: −4x(2xy+3)+5y(2xy+3)

blank 2: (2xy−3)(4x+5y)

blank 1: −2xy(4x+5y)−3(4x+5y)

blank 2: (2xy+3)(4x−5y)

blank 2: −(2xy+3)(4x−5y

need proof for points
