Answer:
(a) x = -0.418 , -3.581
(B) c = 6.855, -1.855
Step-by-step explanation:
(A) We have given equation
On comparing with standard quadratic equation
a = 2, b = 8 and c = 3
So roots of the equation will be
(b)
a = 1, b = -5 and c= -14
So
15mph
it is going slow
Its C it must be true
=−368q2−23qr+544q+34r
Number 1 is 10 and number 2 is 7
14/2 = 7
7 + 3 = 10
