Question

X^2+3/4x-55/32=0 como se resuelve porfavor es urgente es para la esc

Answer 1

x² + (3/4)x - (55/32) = 0

32x² - 24x - 55 = 0

a = 32 b = -24 c = -55

x = [ -b +- √b² - 4ac ] ÷ 2a

x = [ 24 +- √ (-24)² - 4(32)(-55) ] ÷ 2(32)

x = (24/64) +- (8√119 / 64)

x = (3/8) +- (√119 / 8)

x = (3+√119)/8

o

x = (3-√119)/8
