Using integers, without repeating any numbers, fill in the boxes to create an equation with no solutions.

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Solve: 25 points find the fifth term of an increasing geometric progression if the first term is equal to 7−3 √5 and each term (starting with the second) is equal to the difference of the term following it and the term preceding it.
