Question

n

Answer 1

vertical its right

Answer 2

factoring seems dificult i think its beter to use the quadractic formula

Answer 3

with that formula i got x=0.43 and x= 4.56

Answer 4

Solve the following for x:\[2 x^2-10 x+4=0 \]\[\left\{x\text{=}\frac{1}{2} \left(5-\sqrt{17}\right),x\text{=}\frac{1}{2} \left(5+\sqrt{17}\right)\right\}\]\[\{x=0.438447,x=4.56155\} \]

Answer 5

A plot of\[2 x^2-10 x+4 \]is attached.

Answer 6

\[a x^2+b x+c=0 \]\[\left\{x=\frac{-b-\sqrt{b^2-4 a c}}{2 a},x=\frac{-b+\sqrt{b^2-4 a c}}{2 a}\right\} \]
