Question

16ysquare-4y+25=0 find the discriminant

Answer 1

$Compare \: given \: equation \: 16y^{2}-4y+25 =0 \\with \: ay^{2} + by + c = 0 , we \:get$

$a = 16 , b = -4 \: and \: c = 25$

$Discreminant (D) = b^{2} - 4ac \\= (-4)^{2} - 4\times 16 \times 25 \\= 16 - 1600 \\= - 1584$

Therefore.,

$\red { Discreminant (D)} \green {= - 1584 }$
