Grade 10 Quadratic Equations and Expressions CCSS: HSA-REI.B.4, HSA-REI.B.4b

Let a, b, and c be real numbers with a

$!=$ 0. The solutions of the quadratic equation

$ax^2 + bx + c$ are found by using:

$x = (-b +- sqrt[ b^2 - 4ac)]/(2a)$

$x^2 + 7x + 11 = 0$

$x =( -7 +- sqrt 5)/2$
$x = 3 +- sqrt 7$
x = 3
$x = -1 +- i$
