{7(2x+y)}² - {8(x-3y)}²
{7(2x+y)+8(x-3y)} {7(2x+y) -8(x-3y)}
{14x+7y+8x-24y)} {14x+7y-8x+24y}
(22x-17y) (6x+31y)
I hope this is right and will help you

Step-by-step explanation:
49(2x+y)^2 -64(x-3y)^2
= {7(2x+y)}^2-{8(x-3y)}^2
= {7(2x+y)}-{8(x-3y)} {7(2x+y)}+{8(x-3y)}
= {(14x+7y)-(8x-24y)}{(14x+7y)+(8x-24y)}
= (14x-8x+7y+24y)(14x+8x+7y-24y)
= (6x+31y) (22x-17y)
