i attached the formula to ger the area with the perimeter
Answer:
x1=(-4+5i)/2
x2=(-4-5i)/2
Step-by-step explanation:
4x^2 +16x+49=8
4x^2+16x+49-8=0
4x^2 +16x+41=0
a=4, b=16, c=41
x1=(-b+sqrt(b^2-4ac))/2a
x2=(-b-sqrt(b^2-4ac))/2a
x1=(-16+sqrt(16^2-4*4*41))/2*4
x1=(-16+sqrt(256-656))/8
x1=(-16+sqrt(-400))/8
x1=(-16+20i)/8
x1=(-4+5i)/2
x2=(-4-5i)/2
