Solve by using tables. Give each answer to at most two decimal places. –2x2 – 4 = –8x (1 point) 0.59, 3.41 –3.41, –0.59 1.17, 6.
GenaCL600 [577]

Answer:

x=3.414 and x=0.59 is the desired answer.

Step-by-step explanation:

We are given a quadratic equation as : -2x^2-4=-8x\\=> 2x^2-8x+4=0

on dividing both side by 2 we have the equation as

x^2-4x+2=0

on solving for the roots of the equation using the quadratic formula we get that x=2\pm \sqrt{2}

x=2+\sqrt{2} and x=2-\sqrt{2}

x=2+1.414 and x=2-1.414

Hence , x=3.414 and x=0.586≈0.59.
