What exactly is meant by the expression 'Completing the Square'? Give an example as part of your explanation.

completing the square is making the expression a bunch of perfect squares in order to solve it easily and find

Step-by-step explanation:

If i have the expression x^2 + 4x + 1 = 0

i move the one to the right side

x^2+4x=-1

then i add b over 2 squared to both sides

that is x^2+4x+4=3

now i would simply take the square root of both sides of this equation,

(x+2)^2=positive or negative 1.73

x+2=-1.73

x+2=1.73

then you subtract or add to solve for both possible values of x

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
