(-5-square root -7)^2

May 26th, 2015

(-5-square root -7)^2

(-5-square root(-7)*(-5-square root(-7)

-5*(-5-square root(-7)-square root(-7)*(-5-square root(-3))

multiplying out those terms gets:

25+5*square root(-7)+5*square root(-7)+square root(-7)*square root(-7)

combine like terms together

25+10*square root(-7)+(square root(-7))^2

simplify this further to get:

25+10*square root(-7)-7=18+10*square root(-7)]
