Question 841546
Solution :
 Complete the table of values for y=2x^2 + 2x - 3
The values can be find by plugging the x values in the equation which gives us the y value ,

x  -2  -1  0  1  2

y  1   -3 -3  1  9

(b)  Plot the points on the graph and join by a smooth curve. 

(c)  The line y=1 will be passing through 1 and parallel to x-axis.

(d)  solve 2x^2 + 2x - 3 = 1
     Subtract 1 from both the sides , 
     2x^2 + 2x - 2 = 0
     Factoring out the 2 from the equation , 
     2(x^2 + x - 1) = 0 
      x^2 + x - 1 = 0 
Apply the quadratic formula {{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}

    x=(-1-sqrt(5))/2 and x = (-1+sqrt(5))/5
       

Thank you.
