If a quadratic polynomial y = ax2 + bx + c intersects x axis at a and β, then
(i) 2x² + 14x - 16 = 0
(ii) y² – y – 12 = 0
I. 5x2 – 7x – 6 =0
II. 2y2 – 5y – 7 =0
I. x2 + 16x + 63 = 0
II. y2 + 2y - 15 = 0
I. x2 = 10
II. y2 - 9y + 20 = 0
...I. 2y² - 35y + 132 = 0
II. 2x² - 31x + 110 = 0
I. x2 – 3(x + 5) = -11
II. y2 – 4(y + 2) = -2y
I. 2y2 - 15y + 18 = 0
II. 2x2 + 9x - 18 = 0
I. p2 +7p + 10 = 0 II. q2- q – 6 = 0
