Question
Solution
I. 12 x ² - 3 x – 15 = 0
II. 2 y² + 12
Between what values of x is the expression 19x - 2x2Â - 35 positive?
I. x2 – 3(x + 5) = -11
II. y2 – 4(y + 2) = -2y
(i) 2x² – 9x + 10 = 0
(ii) 4y² – 12y + 9 = 0
I. x2 – 13x + 36 = 0
II. 3y2 – 29y + 18 = 0
I. 2b2 + 31b + 99 = 0
II. 4a2 + 8a - 45 = 0
I. 77x² - 25x – 72 = 0
II. 42y² + 13y – 42 = 0
Solve the given two equations and answer the two questions that follow as per the instructions given below.
I. (1/4) + 7.5p(-2) = 3.62...
I. √(17x) + √51 = 0  Â
II. √(4y) + 3 = 0
