Answer 1

Answer:

a^2-b^2= -32

Step-by-step explanation:

I hope you understood

Answer 2

Answer:

-32

Step-by-step explanation:

a-b=-8

ab=-12

$(a-b)^{2}$=$a^{2}$-2(ab)+$b^{2}$

64=a^{2} - (-24) + b^{2}

64-24=a square+b square

$a^{2}$+$b^{2}$=40

ab= -12

$(a+b)^{2}$=b^{2}+a^{2}+2(ab)

=40+(-24)

=16

therefore,

(a+b)=root of 16

=4

Since we got the value of (a+b) and (a-b)

we can find $a^{2}$-$b^{2}$=(a+b)(a-b)

=4*(-8)

=-32

Hope this helps!
