Hello, we need to see it as a difference of two squares as we know that for all a and b real numbers

So, here

Voila !
Thank you
Answer:
p(7) = 57
Step-by-step explanation:
Because this is a function, all you have to do is input 7 for x like so:
p(x)=x^2+x+1 ---------------> p(7)=7^2+7+1
so 49 + 8
= 57
Do 6.5” divided by 5 to find the slope . Then plot each point and
Answer:
perpendicular
Step-by-step explanation:
The equation of the tangent line can be found using slope formula and fact that slope = dy/dx.

where (x0,y0) is point A ---> (0,-1)
Then rearrange equation into slope-intercept form:

Finally sub in x=0 into dy/dx to get slope at the point (0,-1)
