Answer:

x = 4 ± √13

Step-by-step explanation:

x² − 8x + 3 = 0

Complete the square. (-8/2)² = 16.

x² − 8x + 16 − 13 = 0

(x − 4)² − 13 = 0

(x − 4)² = 13

x − 4 = ±√13

x = 4 ± √13

Someone help!! With this question please

Anastasy [175]

You’re trying to get the first equation to equal y so you can substitute it in the second question

2x + y = -2
subtract 2x from both sides: y = -2 - 2x
rearrange the equation : -2x -2
so the answer is C
