Question

EXERCISE 4.3
1. Find the roots of the following quadratic equations, if they exist, by the method of completing the square:
(1) 2x2 - 7x + 3 = 0
(ü) 2x²+x-4=0
(ii) 4x2 +4 3x + 3 = 0
(iv) 2x2 + x +4=0
2. Find the roots of the quadratic equations given in Q.1 above by applying the quadratic
formula.​

Answer 1

Step-by-step explanation:

first you have to compare with equation ax²+bx+c=0

then a = 2 b= -7 c= 3

then put formula x= -b ±√b²-4ac / 2a

then you can solve get the roots of the equation
