2.10 - (4 points)

1. would you factor out the gcf, use the perfect square trinomial pattern, or the difference of squares pattern?
4x^2 - 25
2. show how you would use the approach you picked by factoring this binomial.

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

What function has a range {yly< 5}? question on picture above^
