Step-by-step explanation:
When Delta(b^2-4ac) is greater than 0, the quadratic equation has two distinct real solutions, when it is equal to 0, the quadratic equation has one real solution, when it is negative, it has no real solutions.
Answer:
5m x 5m, 6m x 4m and 7m x 4m
in interval of 0.02 and for the same value of m.
x <= -5
4x + 12 <= -8
4x <= -20
x^2 - 25 ✔
(x+5)(x-5)
x(x-5) +5(x-5)
x^2 - 5x + 5x - 25
x^2 - 25
