Question
Swati drives 55 kms towards East, turns right and drives
50 kms, then turns left and drives 30 kms. In which direction is she facing now? Study the following information carefully and answer the questions below-:Solution
I. 4p² + 17p + 15 = 0
II. 3q² + 19q + 28 = 0
The quadratic equation (p + 1)x 2 - 8(p + 1)x + 8(p + 16) = 0 (where p ≠-1) has equal roots. find the value of p.
I. 2x² - 9x + 10 = 0
II. 3y² + 11y + 6 = 0
I). p2 + 8p + 15 = 0
II). q2 + 9q + 20 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 32x + 252 = 0
Equation 2: y² - 30y + 221 = 0
I. (4x-5)3Â +Â 1/(4x-5)3Â = 2
II. 2[(y+1/y)2- 2]- 9(y+1/y)= -14
(i) 2x² + 14x - 16 = 0
(ii) y² – y – 12 = 0
I. 2x² + 15 x - 27 = 0
II. 3 y² + 25 y - 18 = 0
I. 84x² - 167x - 55 = 0
II. 247y² + 210y + 27 = 0
I. Â 2(x+2)+ 2(-x)=5
II. Â (1/(y+1)+ 1/(y+5))=(1/(y+2)+ Â 1/(y+4))
