The question is which set(s) of algebra tiles could represent the trinomial x^2+2x-5 and somebody help

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Put the equation in slope intercept form by solving for y

3x + 4y = 5 x- 3y = -7 solve by substitution
