Rearrange into the form: (x−4)2 +(y−3)2 = 22 to identify the centre (4,3) and radius 2 ... Find the equations of the circles that have centre (0,0) and touch the circle x2 + y2 − 8x − 6y + 24 = 0. This does not need calculus, just a theorem from euclidean geometry. The given circle has centre (4,3) and radius 1 unit. It isn't easy to immediately see how $2x^2-1$ can factor (or if it can) but $2x^2 - 1 \equiv 2x^2 + 6\equiv 2(x^2 +3)$ so if we can find $-k^2 \equiv 3\pmod 7$ we can have a difference of squares. $3 \equiv -4.. $ and ... that was quick. So $2x^3+5x^2 + 6x + 1\equiv (2x^2-1)(x-1)$ $\equiv 2(x^2+3)(x-1)\equiv 2(x^2 -4)(x-1)$ $\equiv 2(x+2)(x-2 ...Algebra. Simplify (2x)^2. (2x)2 ( 2 x) 2. Apply the product rule to 2x 2 x. 22x2 2 2 x 2.
