URGENT!! WILL GIVE BRAINLIEST Carianne uses the steps in the table to transform the quadratic equation from standard form to vertex form. Which best describes the accuracy of Carianne's work?

Her work and vertex form equation are correct.
She made an error when determining the square of half the coefficient of x.
She made an error when using the zero pair.
She made an error in factoring.

She made an error when using the zero pair.

Step-by-step explanation:

In step 2, Carianne added 4 to the right side and subtracted 4 on the left side, which is completely changing the equation. By definition, your zero pair must have a difference of zero. She need to add 4 to both sides to continue; when manipulating algebra you need to do the same thing to both sides of an equation, otherwise you're just changing the equation.

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )

did you get the answer?
