Answer 2

$(x+3)^2=x^2+6x+9\\\\(a+c)^2=a^2+2ac+c^2\\\\(7-b)^2=49-14b+b^2\\\\(5a+3)=25a^2+30a+9\\\\(6+2c)^2=36+24c+4c^2\\\\(5t+8z)^2=25t^2+80tz+64z^2\\\\(a^2-5)^2=a^4-10a^2+25\\\\(a^2-b^2)^2=a^4-2a^2b^2+b^4$

$(x+8)^2=x^2+16x+64\\\\(t-5)^2=t^2-10t+25\\\\(z-1)^2=z^2-2z+1\\\\(3y-4)^2=9y^2-24y+16\\\\(2a-3b)^2=4a^2-12ab+9b^2\\\\(-3x+y)^2=(y-3x)^2=y^2-6xy+9x^2\\\\(a-b^3)^2=a^2-2ab^3+b^6$
