Solve each equation by factoring. 7x²243=0 I know I'm supposed to add 243 to the other side but don't know what else to do. Divide maybe? Thanks in advance. 243+7x^2= 0 (reorder) 243+243+7x^2 = 0+243 (add 243 to both sides)

Find X 27^4x2=243^3x+6 Please explain how to do it. Thanks 27^(4x2)=243^(3x+6) Notice that 27 and 243 are both multiples of 3 Changing them.. (3^4)^(4x2)=(3^6)^(3x+6) 3^4(4x2)= 3^6(3x+6) taking the log base 3 of each side.
