Read each sentence to find out whether there is any grammatical error in it. The error, if any, will be in one part of the sentence. Mark the part with the error as your answer. If there is no error, mark ‘No error’ as your answer (Ignore the errors of punctuation, if any).Solution
used should be replaced by have been using.
I. 3x2 = 2x2 + 9x – 20
II. 3y2 = 75
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 19x² - 92x + 73 = 0
Equation 2: 17y² - 76y + 59 = 0
In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer Â
I. 3x² –7x + 4 = 0�...
I. x2 – 7x + 12 = 0
II. y2 – 7y + 10 = 0
I. 63x² + 146x + 80 = 0
II. 42y² + 109y + 70 = 0
I. 3x2 – 17x + 10 = 0
II. y2 – 17y + 52 = 0
I. x2 + (9x/2) + (7/2) = - (3/2)
II. y2 + 16y + 63 = 0
I. 40 x² - 93 x + 54 = 0
II. 30 y² - 61 y + 30 = 0
I. 2x² - 7x + 3 = 0
II. 8y² - 14y + 5 = 0
I. 10p² + 21p + 8 = 0
II. 5q² + 19q + 18 = 0
