<u>Answer:</u>

The method that finds the total yards at the end of the first four plays is \boldadd (-12) to (3\times5)\bold yards.

<u>Solution: </u>

Teen lost 12 yards on the first play, so in first play the yards goes in negative.

Next three plays each he gained 5 yards each.  Total yards he got is (5\times3) yards . As he gained the yards, so these yards will be positive.

So after four play the total yards will be -12+3\times5

Hence, the method is add (-12) to (3\times5)

Solve for x use the completing the square method x^2+6x=5
Mrac [35]

Answer:

x_{1} =-3 +\sqrt{14} \\\\x_{2} =-3 -\sqrt{14}

Step-by-step explanation:

x^{2}+6x-5=0

we divide the coefficient of the X by half :

in this case: 6/2 = 3 , then we do the following

The result obtained is raised to square power:  3^2=9

we sum and subtract by 9 to maintain the balance of the equation:

x^{2}+6x+9-9-5=0

we have:

(x+3)^{2}-9-5=0

(x+3)^{2} = 14

lets apply square root on both sides of the equation:

\sqrt{(x+3)^{2}}=\sqrt{14}

we know:

\sqrt{a^{2}} = abs(a)

so we have:

abs(x+3)=\sqrt{14}

from where two solutions are obtained

x_{1} + 3 =\sqrt{14} \\\\x_{2} + 3 =-\sqrt{14}

finally we have:

x_{1} =-3 +\sqrt{14} \\\\x_{2} =-3 -\sqrt{14}

You move the decimal point forward until it reaches the one so it looks like this:

1.4 x 10⁵ 

the exponent, 5, just tells you how many spaces the decimal point moved.
