PLZ HELP 5. How many real number solutions does the equation have?

0= -4x^2+7x+8

A) two solutions
B) one solution
C) no solutions
D) infinitely many solutions

6. How many real number solutions does the equation have?

0= 3x^2+18x+27

  5.  A) two solutions

  6.   one solution

Step-by-step explanation:

5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:

  b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number

When the discriminant is positive, there are two real solutions.

6. The equation factors as ...

  0 = 3(x +3)^2

This will have one real solution at x=-3.
