ADRATIC EQUATIONS
EXERCISE 4.4
1. Find the nature of the roots of the following quadratic equations. If the real roots exi
find them:
(1) 2x - 3x + 5 = 0
(ii) 3x2 -4 73 x+4=0
(ii) 2x2 - 6x +3=0
Find the values of k for each of the following quadratic equations, so that they have
equal roots.(i)2x2 +kx+3
(ii) kx (x - 2)+6=0
​

Answer 1

Answer:

2x²-3x+5

Step-by-step explanation:

2x²-5x+2x+5

x(2x+5)+1(2x+5)

(x+1) (2x+5)

Roots are ...

x+1=0

x=(-1)

2x+5=0

2x=0-5

2x=5

x=5/2

Roots are (-1) and 5/2
