THANK YOU

 

Answer:

(s+4)²

=(s+4)(s+4)

=(s)(s)+(s)(4)+(4)(s)+(4)(4)

=s²+4s+4s+16

=s²+8s+16

(w+5)²

=(w+5)(w+5)

=(w)(w)+(w)(5)+(5)(w)+(5)(5)

=w²+5w+5w+25

=w²+10w+25

(e−7)²

=(e−7)(e−7)

=(e)(e)+(e)(−7)+(−7)(e)+(−7)(−7)

=e²−7e−7e+49

=e²−14e+49

(3z+2k)²

=(3z+2k)(3z+2k)

=(3z)(3z)+(3z)(2k)+(2k)(3z)+(2k)(2k)

=9z²+6kz+6kz+4k²

=4k²+12kz+9z²
