I. x2 - 17x + 70 = 0 => x2 - 7x – 10x + 70 = 0 => x(x – 7) – 10(x – 7) = 0 => (x – 7) (x – 10) = 0 => x = 7, 10 II. y2 - 11y + 28 = 0 => y2 - 7y – 4y + 28 = 0 => y(y – 7) – 4(y – 7) = 0 => (y – 7) (y – 4) => y = 7, 4 Hence, x ≥ y.
Find the area between the lines 18x +12y = 108, 9x + 6y = 27, x - axis and y -axis.
For which value of m, there is no solution to the equation -
a – b = 5
ma – 4b = 1
The ratio of roots of an equation
ax²+bx+b = 0 is p : q
Then find, √p/√q + √q/√p + √p/√q ?
I. 2p2 + 5p + 2 = 0 II. 2q2 + 11 q + 14 = 0
I. 8/(√x) + 6/(√x) = √x
II. y ³- (14)7/2 /(√y) = 0
I. p2 – 5p + 6 = 0
II. 36q2 = 81
