The L.C.M. of (2x2 - 3x - 2) and (x3 - 4x2 + 4x) is ________
2x2 - 3x - 2 = 2x2 - 4x + x - 2
2x(x - 2) + 1(x - 2)
(x - 2)(2x + 1)
x3 - 4x2 + 4x = x(x2 - 4x + 4)
x(x - 2)2
LCM = x(x - 2)2(2x + 1)
2. If x + y = 10 and xy = 4, then what is the value of x4 + y4?
3. Find the value of x and y: (7x + 3y = 44) and (x + 5y = 20)
4. If 7 + 3x ≥ 5 -$\frac{x}{2}$ and 2x + 3 ≤ 5 - 2x; then x can take which of the following values?
5. If $7x - \left(\frac{3}{2}\right) * (4x - 9)$ = 6.5, then the value of x is?
6. If $a^{2}+b^{2}+c^{2}$ = 14 and a + b + c = 6, then the value of (ab + bc + ca) is,
9. If xy = 22 and $ x^{2} + y^{2}$ = 100, then what will be the value of (x + y)?
