X ^ 2 + 4x - 7 = 0<br><br> Solve using the Quadratic Formula
aalyn [17]

There's a special case of the quadratic formula called the Shakespeare Quadratic Formula (2b or -2b) that applies when the linear coefficient is even.

x^2-2Bx + C \textrm{ has zeros }x = B \pm\sqrt{B^2 - C}

If you're planning on solving a lot of quadratic equations quickly, it's good to know.

Here we have

x^2 + 4x - 7 = 0

so

x = -2 \pm \sqrt{2^2 - -7}

x = -2 \pm \sqrt{11}

Which rule describes the composition of
ExtremeBDS [4]

Answer:

The second one: r x-axis. R 90(x,y)

Step-by-step explanation:

You can see that from ABC to A'B'C', it's rotated a positive 90 degrees. then, from A'B'C' to A"B"C", reflected across x-axis. and when writing the transformation, it goes by last to first. that's why the R 90 comes first.
