Solve the quadratic equation 2x^2-5x+1=x+4​

Mathematics
1 answer:
Mariulka [41]3 years ago
3 0

Answer:

Step-by-step explanation:

Combine like terms in 2x^2-5x+1=x+4:  2x^2 -6x - 3 = 0

The coefficients of this quadratic are {2, -6, -3}.  Apply the quadratic formula.  Start by finding the discriminant, b^2 - 4ac:

b^2 - 4ac = (-6)^2 - 4(2)(-3) = 36 + 24 = 60

Because the discriminant (60) is positive, we know that this quadratic has two real, unequal roots:

      -(-6) ± √60          6 ± (√4)(√15)

x = -------------------- = ----------------------

             2(2)                         4

or:

      6 ± 2√15            3 ± √15

x = -----------------  =  ----------------

              4                       2

Anni [7]

Answer:

Answer:

Green box contains more sugar.

Step-by-step explanation:

Consider the provided information.

Ashley found 2 boxes of sugar in the kitchen.

The green box says 1.26 kg and the red box says 1.026 kg.

we need to find which box contains more sugar.

To find this we will first check the digit at ones place.

Both the digit has 1 at the ones place. So now check the digit at tenths place.

1.26 has 2 at tenths place while 1.026 has 0 at tenths place.

As we know 2 is greater than 0, thus the number 1.26 is greater than 1.026.

Hence, green box contains more sugar.
