If the diagonals of the parallelogram intersect with each other, this means that the diagonals bisect each other. Thus,
AE = CE
Substituting the equations,
2x² - 3x = x² + 4
The values of x from the equation are equal to 4 and -1.
AE = 2(4)² - 3(4) = 20
Hence, AC is equal to 40.
Answer: 40 units
Hello there, you can proceed with the multiplication of these factors using the FOIL method (which stands for first, outer, inner and last) multiply I assume that by descending order, you mean by decreasing power. If it were so, the answer is 6(x^3)12(x^2)-16(x^2)32x-27x+72.
