Question 141205: Hi, I have two problems I am not sure about. I hope some one can help me please.
Solve using the quadratic formula:
x2 – 3x = -6x – 1
Solve using the quadratic formula:

Given: +x%5E2+%96+3x+=+-6x+%96+1
+x%5E2+%2B3x+%2B1+=+0
Now you use the quadratic equation with a=1, b=3 c =1
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

Given: +x%5E2+%96+10x+%96+1+=+-10
+x%5E2+%96+10x+%2B+9+=+0
Now you use the quadratic equation with a=1, b=-10 c =9
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
