1.	Find the roots of the following quadratic equations. By factorisationx²-3x-10=0
Answer» Gaurav, you always help everyone. I want to know your class. Can you please.... x2\xa0– 3x\xa0– 10=\xa0x2\xa0- 5x\xa0+ 2x\xa0- 10=\xa0x(x\xa0- 5)\xa0+ 2(x\xa0- 5)= (x\xa0- 5)(x\xa0+\xa02)Roots of this equation are the values for which\xa0(x\xa0- 5)(x\xa0+\xa02) = 0∴\xa0x\xa0- 5 = 0 or\xa0x\xa0+ 2 = 0⇒\xa0x\xa0= 5 or\xa0x\xa0= -2
