Q:
# Which equation could be solved using the graph above?X^2+4x+3=0X^2-4x+3=0X^2-6x+9=0X^2-1=0

Accepted Solution

A:

Answer:X²+4x+3=0Step-by-step explanation:y = X² + 4x + 3 y = 0Solution:x = -3, x² = -1Steps:X² + 4x + 3 = 0write 4x as a sumX²+ 3x + x + 3 = 0Factor out x from expressionX (x + 3) + x + 3 = 0Factor out x + 3 from expression(x + 3) x (x + 1) = 0When the product of factors equals 0, at least one factor is 0x + 3 = 0x + 1 = 0solve for xx = -3x + 1 = 0solve for xx = -3x = -1The final solutions areX = -3, X² = -1
