Use the discriminant to determine whether the equation has t

Use the discriminant to determine whether the equation has two distinct real solutions solution. x^2 + 7x + 5 = 0 Choose the correct answer below. The equation has two distinct real number solutions. The equation has no real number solution. The equation has one real number solution. Determine whether the given ordered pair is a solution to the given equation. (6.13); y = 4x - 9 Is the given ordered pair a solution to the given equation? Yes No Solve by using the squareroot property. (x - 2)^2 = 49 Factor the trinomial completely. -q^2 - 14q - 45 Select the correct choice below and, if necessary, fill in the answer box within your choice. -q^2 - 14q - 45 = The polynomial is prime. The area of the figure to the right is (x + 8)(x + 9). Find another expression for this area by finding the sum of the areas of the smaller rectangles.

Solution

1.)x^2+7x+5=

a=1,b=7,c=5

Discriminat D=b^2-4ac

D=49-4*1*5=29

If D > 0, then the quadratic equation has 2 distinct solutions.
