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

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:

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

1/4 because there is 4 grades.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
