Note: In active voice, the subject of the verb is doing the action, but in passive voice the subject of the verb is being acted on. To change a sentence to passive voice, make the object the subject and use the correct form of the verb 'be' with the past participle of the main verb. According to the rules of active voice this is the most appropriate option.
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ is
...I. 6 y² + 11 y – 7= 0
II. 21 x² + 5 x – 6 = 0
I. 2x2 + 12x + 18 = 0
II. 3y2 + 13y + 12 = 0
Equation 1: 2x2 - 21x + 54 = 0
Equation 2: 4y2 - 23y + 15 = 0
Difference between the roots of equation 1 is approx...
I. y² - 7 y – 18 = 0
II. x² + 10 x + 16 = 0
I. x² - 208 = 233
II. y² + 47 - 371 = 0
I. 104x² + 9x - 35 = 0
II. 72y² - 85y + 25 = 0
In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer
I. 7x² - 19x + 10 = 0...
I. 15b2+ 26b + 8 = 0
II. 20a2+ 7a - 6 = 0
I. x² + 3x – 154 = 0
II. y² + 5y – 126 = 0
