B^2 - 4xaxc
a=3 b= -10 c= -8

(-10)^2 -4 x3 x (-8)

100 + 96

196

Sqrt(196) = 14

x1 = (-b-sqrt(196))/2a
x1= (10-14)/6
x1= -2/3

x2 = (-b+sqrt(196))/2a
x2 = (10+14)/2a
x2= 4

What number should be placed in the box to help complete the division calculation? Long division setup showing an incomplete cal
lianna [129]

Answer:

The unknown value is being subtracted from 226 is 160

Step-by-step explanation:

Long division setup showing an incomplete calculation

  • 16 is in the divisor
  • 3426 is in the dividend
  • 2 hundreds and 1 tens is written in the quotient
  • 3200 is subtracted from 3426 to give 226
  • An unknown value represented by a box is being subtracted from 226

so,

The dividend = 3426

 The divisor = 16

2 hundreds means 200 and 1 tens means 10

∵ The quotient = 200 + 10 + x

∵ Dividend = divisor × quotient

∴ (16 × 200) + (16 × 10) + (16 × x) +remainder  = 3426  

∵ 16 × 200 = 3200

Subtract 3200 from the dividend  

∴ 3426 - 3200 = 226

∵ 16 × 10 = 160

∴ 226- 160 = 66

⇒160is the unknown value

∵ 16 × x = 16x  

∵ 66 - 16x = 0

∴ 66 = 16x

- Divide both sides by 16

∴ x = 4  and remainder = 2

∴ 3426 ÷ 16 = 200 + 10 + 4

∴ 3426 ÷ 16 = 214  

∴ From the steps above the missing number subtracted from

  226 is 160

The unknown value is being subtracted from 226 is 160
