Expand
Using a2-b2 formula

Answer 1

Hey mate!!

$<font color="purple"><b>$

Formula=$a{}^{2}-b{}^{2}$

=>(a+b)(a-b)

(2z+3x+5y)(2x+3x-5y)

$(2z+3x){}^{2}-(5){}^{2})$

=>(2z+3x+5y) (2z+3x-5y)

Hope it's help uh

Answer 2

HELLO!!!

$((2z + 3x) + 5y)((2z + 3x) - 5y)$

By , a^2-b^2=(a+b)(a-b)

$(2z + 3x) {}^{2} - {(5y)}^{2}$

$({(2z)}^{2} + {(3x)}^{2} + 2(2z)(3x)) - 25 {y}^{2}$

$(4 {z}^{2} + 9 {x}^{2} + 12xz) - (25y {}^{2} \: )$

HOPE IT HELPS UHH #CHEERS
