Answer:
1. x^2 + 4x - 12 = 0
2. 2x^2 + 4x - 6 = 0
Step-by-step explanation:
1. x (x + 4) = 12
x^2 + 4x = 12
x^2 + 4x - 12 = 12 -12
x^2 + 4x - 12 = 0
2. (x + 6)^2 + (x - 4)^2 = 58
x^2 + 12x + 36 + x^2 - 8x + 16 = 58
2x^2 + 4x + 52 = 58
2x^2 + 4x + 52 - 58 = 58 - 58
2x^2 + 4x - 6 = 0

Answer:
x_{1}\\ =6
x_{2}\\ =2
Step-by-step explanation:
X(x+4)=12
x^2+4x=12
x^2+4x-12=0
x=(-4±√(4^2-4∙1(-12)))/(2∙1)
x=(
x=(-4±√(16+48))/2
x=(-4±8)/2
x=(-4+8)/2
x=(-4-8)/2
Calculate
x=(-4+8)/2
x=2
x=(-4-8)/2
x=-6
Answer:
x_{1}\\ =6
x_{2}\\ =2
