Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 2 1 cannot be determined

Steps:Discriminant Formula: D = b² - 4ac (With a = x² coefficient, b = x coefficient, and c = constant)

So to find the number of solutions this quadratic equation has without actually solving the equation, we are going to be using the discriminant formula. Plug in the numbers and solve:

Now, here are the rules with discriminants:

D > 0; there are 2 real solutions in the equationD = 0; there is 1 real solution in the equationD < 0; there are no real solutions in the equation

Since -3 is less than 0, this means that there are 0 real solutions in this equation.

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°
