Answer 1

Answer:

I will answer only a few questions since you should ask one question at a time

$1) 100-9p^2$

$(10)^2 - (3p)^2$

$(10+3p)(10-3p)$

$5) x^2-0.25$

$x^2-(0.5)^2$

$(x+0.5)(x-0.5)$

$19) x-y-x^2+y^2$

$x-y-(x+y)(x-y)$

$(1-x-y)(x-y)$

$8) 4x^2-3$

$(2x)^2-(\sqrt{3})^2$

$(2x+\sqrt{3})(2x-\sqrt{3})$

$7)1-100a^2$

$(1)^2-(10a)^2$

$(1+10a)(1-10a)$
