A tv screen is 2 inches longer than it's height. If the diagonal length of the screen is 2 inches more than it's length, what is the diagonal measurement of the screen?

Question

anonymous · Answer

put height = x, length = x+2 and diagonal = x+4 then use pythatoras
$$x^2+(x+2)^2=(x+4)^2$$

anonymous · Answer

$$x^2+x^2+4x+4=x^2+8x+16$$
$$2x^2+4x+4=x^2+8x+16$$
$$x^2-4x-12=0$$

anonymous · Answer

$$(x-6)(x+2)=0$$
$$x-6=0$$
$$x=6$$ we can ignore the other answer because it is negative
