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,
Find the zeros of the function by using the quadratic formula. Simplify your answer as much as possible. g(x)= 2x^2+4x-12
a carpenter had a 20 ft piece of lumber which he cut into 3 pieces. one piece was 7 1/3 ft long and other was 6 1/2 ft long. how long was the remaining piece?
2x+y/x+3y=-1/7and 7x+36y=47/3 hence find p if xy=p=x/y
Horizontal Shifts These are quite simple as well though there is one bit where we have to be careful. Given the graph of f ( x ) the graph of g ( x ) = f ( x + c ) will be t
4 __ -3 4
4x/y-3x/y+5x/y-x/y
Sabrina invested 1500000 in stocks and bonds.Her investment in bonds is 5000 more than half her investment in stocks.How much did she invest in each ?
why is the inequality symbol must be reversed when both sides of a inequality are multiplied or divided by a negative number
how do you do it i do not understand at all
y=-x-2 y=-5x+2
