What is the discriminant of 3x^2-8x+5=5x^2

1 answer:

6 0

Move all terms to the left side of the equation and simplify.

−2x2−8x+5=0-2x2-8x+5=0

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

b2−4(ac)b2-4ac

Substitute in the values of aa, bb, and cc.

(−8)2−4(−2⋅5)-82-4-2⋅5

Evaluate the result to find the discriminant.\

Let v = 3i + 2j and w = 2i + 3j. Sketch v, w, v + w, 2w, and v − w in the plane

Nimfa-mama [501]

Answer:

Step-by-step explanation:

In the argand plane for plotting points of complex numbers we take i coefficient as x and j coefficient as y and plot as we plot regular points on the graph.

v=3i+2j

Point is (3,2) A

w =2i+3j , Point is (2,3) B

v+w = 5i +5j Point is (5,5) C

2w = 4i+6j , point is (4,6)

v-w = i-j Point (1,-1)

Please find enclosed the above points plotted on the graph.
