Question

Find the roots of quadratic equation
2x +48 - 4 =0 using
Sormula method
​

Answer 1

$2x + 48 - 4 = 0 \\ a = 2 \: \: \: b = 48 \: \: \: c = - 4 \\ x = - b + - \sqrt{} b {}^{2} - 4ac \div 2a \\ = - 48 + - \sqrt{}48 {}^{2} - 4 \times 2 \times - 4 \div 2 \times 2 \\= - 48 + - 56 \\ x= - 48 + 56 /4\: \: \: \: \: or \: x = - 48 - 56 /4\\ x =8/4 \: \: \: \: \: \: \: or \: x = - 104/4$

x=2 or x=-26

Therefore,X=4 or X=-26

HOPE IT HELPS YOU DEAR..........
