Correct option is D
Given:
Two quadratic equations:
2x2+19x+45=0………….(i)
2y2+11y+12=0………….(ii)
Solution:
For equation (1).
2x2+19x+45=0
2x2+10x+9x+45=0
2x(x + 5) + 9(x + 5) = 0
(2x + 9)(x + 5) = 0
2x + 9 = 0 or x + 5 = 0
x =
2−9 = -4.5 or x = -5
x = -4.5, -5
For equation (2)
2y2+11y+12=0
2y2+8y+3y+12=0
2y( y + 4) + 3(y + 4) = 0
(2y + 3)(y + 4) = 0
2y + 3 = 0 or y + 4 = 0
y =
2−3= - 1.5 or y = - 4
y = -1.5, -4
Now, comparing values of x and y
x = -4.5, -5
y = -1.5, -4
Thus, we can see x < y.
