Question

(b² - a²) (x²+1)= 2(a²+b²)x then the value of x​

Answer 1

Step-by-step explanation:

x2-5px+16=0 has no real roots,is

a) p>o b)p<0 c) -8/5 <p< +8/5 D) -8/5<_ p<o

2 determine the roots of the following quadratic equation :

x2 - 2(a2 +b2) x+(a2-b2)2= 0

3 if the eqution (1+m2)x2+ 2mcx +(c2-a2)=0 has equal roots ,prove that c2=a2(1+m2)
