+1766 Find the constant p such that x2−5x−2x+3x2−11x+p is the square of a binomial.
+37165 Simplify to
4x^2 -18x Divide out '4' so you can complete the square for 'x'
4 ( x^2 - 4.5x ) Now complete the square
4 ( x- 2.25)^2 - 20 .25 Now you can see that p = - 20.25
+37165 Sorry... that should be
4 ( x- 2.25)^2 - 20 .25 + p SO p would need to be + 20.25 Sorry for my error !
