n^2+8n+12 factoring

Physics
I'm unsure of how to figure out the potential at the different corners because if the first distance is kq/1.5, why isnt the 2nd one kq/1.5? Im doing (9e9)(2.00e-6)/1.5=12000, which I dont know which number that is, or what to do with it further?

Two identical point charges are fixed to diagonally opposite corners of a square that is 1.5 m on a side. Each charge is +2.0 µC. How much work is done by the electric force as one of the charges moves to an empty corner? I have W(fe)= -EPE=-q[V(f)-V(i)]. I can't fig...

the perimeter of a triangle is 51 centimeters, the longest side is 1 centimeter less than the sum of the other two sides. twice the shortest is 11 centimeters less than the longest side. find the lengths of each side of the triangle.

Megan factored the expression -12x^2 +52x-35as (-2x+5)(6x-7). But when Jacob applied the FOIL principle and multiplied out (-2x+5)(6x-7), he got -12x^2+44x-35; thus, Meganâ€™s solution does not appear to check. Why is that? Please help Megan to understand this ...

Andrew factored the expression 20x^3-12x^2+8x as 4x (5x^2-12x^2+8x). But when Melissa applied the distributive law and multiplied out 4x (5x^2-12x^2+8x), she got 20x^3-48x^3+32x^2; thus, Andrew’s solution does not appear to check. Why is that? Please help Andrew to unders...

the planet Jupiter is more than 300 as massive as earth. But a body would scarecly weighs 3 times as much on the surface of Jupiteras it would on the surface of the earth. Can you think of an explanation for why this is so?
