Let f(x)=2x^2+x-3 and g(x)=x-1. Perform the indicated operation, then find the domain.

Dominik [7]

Multiplying the two functions together using the Distributive Property, we get (2x²+x-3)*(x-1)=2x³+x²-3x-2x²-x+3= 2x³-x²-4x+3. In addition, since any value x can be plugged into 2x³-x²-4x+3, A is your answer!

2=x^2-10x solve by completing the square

amm1812

$2=x^2-10x\\\\\implies x^2 -10x =2\\\\\implies x^2 -2\cdot 5 x +5^2 -5^2 = 2\\\\\implies x^2 -2\cdot 5x +5^2 = 2+5^2 \\\\\implies (x-5)^2 = 27\\\\\implies x-5 = \pm\sqrt {27}\\\\\implies x = \pm\sqrt{27} +5=\pm3\sqrt{3}+5\\\\\text{Hence,}~ x = 5+3\sqrt 3~\text{or}~ x = 5-3\sqrt 3$
