x2 ? 11x + 28=0
x2 ? 7x ? 4x + 28=0
x (x-7) ? 4 (x-7)=0
(x-4) (x-7)=0 x=4, 7
y2 ? 18y + 81=0
y2 ?9y ? 9y + 81=0
y (y-9) ? 9 (y-9)=0
(y-9) (y-9)=0 y=9, 9
So, x<y.
3x2 ? 14x + 16=0
3x2 ?6x ? 8x + 16=0
3x (x-2) ? 8 (x-2)
(3x-8) (x-2)=0
x=8/3 or 2
5y2 ? 16y + 12=0
5y2 ? 10y ? 6y + 12=0
5y (y-2) ? 6 (y-2)=0
(5y-6) (y-2)=0
y=6/5 or 2
Can't be determined.
I. 2x2 + 19x + 42 = 0
2x2 + 12x + 7x + 42 = 0
2x (x+6) + 7(x +6) = 0
(2x+7) (x+6) = 0 x = -7/2, -6 I
I. 4y2 + 43y + 30 = 0
4y2 +40y + 3y + 30 = 0
4y(y + 10) + 3(y + 10) (4y + 3)(y + 10) = 0
y = -3/4, -10
So answer is no relation.
I. x2 + 2x - 195 = 0 = (x+15) (x-13) => x = -15, 13
II. y2 + 30y + 225 = 0 = (y+15) (y+15) => y = -15, -15
So x ? y
I. 2x2 - 13x - 189 = 0 2x2 - 27x + 14x - 189 = 0 x(2x - 27) + 7(2x - 27) = 0 x = -7, 27/2
II. 2y2 - 3y - 189 = 0 2y2 - 21y + 18y - 189 = 0 y(2y - 21) + 9(2y - 21) = 0 y = -9, 21/2
When x, as well as y, have both positive and negative values then no relationship can be established between them because if we consider x to be positive then the negative value of y will be lesser than x. If we consider x to be negative then positive value of y will be greater than x.
As per the BODMAS rule, Addition and subtraction can be treated on same priority (from left to right) when they are in consecutive order.
65% × 700 + 14 - 9 × 3 65 × (700/100) + 14 - 27 455 + 14 - 27 = 442
As per the BODMAS rule, the priority in which the operations should be done is:
Priority wise operations | Symbol |
B-Bracket | () |
O-of | of |
D-Division | /,÷ |
M-Multiplication | *,x |
A-Addition | + |
S-Subtraction | - |
Note: Addition and subtraction can be treated on same priority (from left to right) when they are in consecutive order.
