Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.−b b2 − 4ac 2a

Use the part of the quadratic formula that you chose above and find its value, given the following quadratic equation:

4x2 + 6x + 2 = 0

Numerical Answers Expected!

Answers

Hello,

if b²-4ac>0 then the equation has 2 reals roots
if b²-4ac=0 then the equation has one real root with multiplicity 2
if b²-4ac<0 then no real root.

4x²+6x+2=0

Δ=6²-4*4*2=36-32=4=2² ==> 2 reals roots

==>x=(-6-2)/8=-1 or x=(-6+2)/8=-1/2

One other way is:

4x²+6x+2=0
==>2(2x²+3x+1)=0
==>2x²+3x+1=0
==>2x²+2x+x+1=0
==>2x(x+1)+1(x+1)=0
==>(x+1)(2x+1)=0
==>x=-1 or x=-1/2

It is estimated that there are 1.2×1057 atoms in the Sun. The number of atoms in the rest of the Solar System is approximately 1.2×1056. About how many more atoms exist in the Sun than in the rest of the Solar System? Drag numbers to complete the answer in scientific notation.

Answers

Answer:

1.08 * 10^57

Step-by-step explanation:

Given that:

Number of atoms in the sun = 1.2 * 10^57

Number of atoms in the rest of the solar system = 1.2 * 10^56

About how many more atoms exist in the Sun than in the rest of the Solar System?

Subtract the number of atoms in solar system from number of atoms in sun

(Number of atoms in sun - number of atoms in rest of the solar system)

(1.2 * 10^57) - (1.2 * 10^56)

= 1.08 * 10^57 (using calculator)
