well, -12+7 is 5 times (23-7=16) so that answer is 80 and 6-(-5*4=-20) so that is also 16
Answer:
Quadratic Formula x = [-b +- Sq root (b^2 - 4ac)] / 2a
In this example a= 2 b= -6 c= 5
x = [- - 6 +- Sq root ((-6^2) - 4 *2*5)] / 2*2
x = [6 +-sq root (36 -40)] / 4
x = 6 +- 2i / 4
x1 = 1.5 + .5i
x2 = 1.5 -.5i
Step-by-step explanation:
