Question

3. What is the nature of the root of the quadratic equation:4m2 - 8m +9 = 0?
(A) Real
(B) Not Real
(C) Real and equal
(D) Real and unequal​

Answer 1

Answer:

$Hence$ $the$ $roots$ $are$ $not$ $real$

Step-by-step explanation:

$The$ $nature$ $of$ $the$ $equation$ $will$ $be$  $given$ $by$ $the$ $discriminant$:

$Discrimant=b^{2} -4ac$

$if:$

• $b^2-4ac=0$

$then$ $the$ $roots$ $are$ $real$ $and$ $equal$

• $b^2-4ac<0$

$then$ $the$ $roots$ $are$ $not$ $real$ $and$ $complex$

• $b^2-4ac>0$

$then$ $the$ $roots$ $are$ $real$ $and$ $distinct.$

$b^2-4ac$

$(-8)^2-4(4)(9)$

$64-144=-80$

$Hence$ $the$ $roots$ $are$ $not$ $real$ $and$ $complex$.
