Question

Hello brothers and sisters pls.. help me
4x²-176x +5324= 4904​

Answer 1

Step-by-step explanation:

$4x { }^{2} - 176x + 5324 = 4904 \\ 4x {}^{2} - 176x + 5324 - 4904 = 0 \\ 4x {}^{2} - 176x + 420 = 0 \\ x { }^{2} - 44x + 105 = 0 \\ by \: formula \\ d = b {}^{2} - 4ac \\ = (44) {}^{2} - 4 \times 1 \times 105 \\ = 1936 - 420 \\ = 1516 \\ now \\ x = (- b + \sqrt{d} ) \div 2a \\ = (44 + \sqrt{1516} ) \div 2 \times 1 \\ =( 22 + \sqrt{379} )and \: (22 - \sqrt{379})are \: two \: roots \:$

hope you will satisfy.
