Question

solve 30x^2-12550x-97500=0​

Answer 1

Step-by-step explanation:

3x^2-1255x-9750=0

formula x =(-b± (underroot b^2 -4ac))÷2a

x=(-(-1255)± (under root( 1255 )^2- 4(3)(-9750)) ÷2(3)

x = (1255 ± under root '1575025 + 117000 )) ÷ 6

x =( 1255 ± under root 1692025 )÷ 6

X = (1255 ± 1300 )÷ 6

X = 2555 ÷6 = 425.8333 approximately
