For a =-4 and b = 5, value of a² – b² is:
If (x –1.3)3+(x–1.4)3+(x–1.5)3 = 3(x–1.3)(x–1.4)(x–1.5), Then x = ?

If x = (2+√3)/(2-√3), y = (2-√3)/(2+√3)
Then find out the value of (x²+y²-xy)/(x²+y²+xy)
- If a 2 + b 2 + c 2 = 240 and ab – bc – ca = 64, then find the value of (a + b – c) 2 .
- Find the value of (21)³ + (- 12) ³ + ( - 9)³.
If a = 7.250, b = 3.258 and c = 3.992 then value of a3-b3-c3-3abc is.
What is the HCF of (x³ + 3x² - x - 3) and (x³ + 4x² + x - 6)?
