Find the indicated product of (2r-5) (2r-5) show your solution :)   using FOIL method (2r-5) (2r-5) First term (2r)(2r) = 4r^2 Outer term (2r)(-5) = -10r Inner term (-5)(2r) = -10r Last term (-5)(-5) = 25 4r^2 - 10r - 10r + 25 4r^2 - 20r + 25 or by using the algebraic property thingie such that (a - b)(a - b) = a^2 - 2ab + b^2 (2r-5) (2r-5) a = 2r b = 5 so 4r^2 - 2(2r)(5) + 25 4r^2 -20r + 25
