By Using the discriminant find out which solution set we obatin for each of the following quadratic equations.
13x2 +1= 5x
Solution
Firstly get the equation in standard form.
13x2 - 5x + 1 = 0
Then we have,
a = 13 b = -5 c=1
Plugging in the discriminant gives,
b2 - 4ac = ( -5)2 - 4 (13) (1) =-27
The discriminant is negative & thus we will have two complex solutions. For reference reason the actual solutions are,
(8x^3+6x^2-8x-15)+(4x-5)
5x+3y=0
How do I do this?? x/x+1=x/2(x-4)
x + y =2 , 2x- y =0
2(5x-4)-6
how to answer
y=2/3x-1
