Question

transform the equation x(x-2) = 4 to a quadratic equation in the form of ax2+bx+c=0

Answer 1

x(x-2)=4

x^2 - 2x =4(multiplying x to (x-2)

x^2-2x-4 =0

Answer 2

Answer:

X(X -2) = 4

x2 - 2X -4 = 0

so by comparing the above equation with

ax2+bx +c =0

then we will find

a = 1, b = -2,c = -4
