Solve the quadratic equation by completing the square. What are the missing pieces to the steps? –27 = 4x2 – 24x –27 = 4(x2 – 6x
IrinaVladis [17]
We have that
4x²<span> – 24x+27=0
</span>

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(4x² – 24x)=-27

Factor the leading coefficient 

4*(x² – 6x)=-27

<span>Complete the square. Remember to balance the equation by adding the same constants to each side

</span>4*(x² – 6x+9)=-27+36--------> missing pieces

Rewrite as perfect squares

4*(x-3)²=9

(x-3)²=9/4----> square root both sides----> (+/-)(x-3)=3/2----> missing pieces

+(x-3)=3/2------> x=(3/2)+3-----> x=9/2

-(x-3)=3/2-----> x=3-(3/2)-----> x=3/2

Total injuries on Turf are 1050 and 4.26% of the total injuries were severe. So find what is the 4.26% of 1050.

4.26% of 1050

Here of means multiplication as usually seen in mathematics.

So we can write:

4.26/100 x 1050
