Can someone please explain to me how to do this question x^2-7x+___=( )^2 thanks

OpenStudy (therealmeeeee):

wat number is it ????

OpenStudy (therealmeeeee):

x^2 -3x -10x + 30 doesn't match - you needed one + sign, one negative sign, with the higher number + so that the middle number is + (x-3)(x+10) x^2 -3x + 10x - 30 x^2 +7x - 30 (now it works)

OpenStudy (therealmeeeee):
