Order the steps for solving this equation using the quadratic formula
X^2 + 3x - 4 = 0

Can someone me do math because i am having a breakdown rn because i don’t get it

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32

Simplify this expression. 8x 16(x + y)
