. Use the quadratic formula to solve each quadratic real equation. Round your answers to two decimal places. If there is no real solution, say so.
a) x^2 - 5x + 11 = 0
b) -2x^2 - 7x + 15 = 0
c) 4x^2 - 44x + 121 = 0

A. No real solution

B. 5 and -1.5

C. 5.5

Step-by-step explanation:

The quadratic formula is:

, with a being the x² term, b being the x term, and c being the constant.

Let's solve for a.

We can't take the square root of a negative number, so A has no real solution.

Let's do B now.

So B has two solutions of 5 and -1.5.

Now to C!

So c has one solution: 5.5

Hope this helped (and I'm sorry I'm late!)

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
