Question 1) Ricky and Tom are doing math together. 1a) Rick thinks this is perfect square trinomial. Tom thinks this is a difference of two squares. Who is correct? [x2 + 8x + 16] · [x2 – 8x + 16] = (x2 – 16)2 1b) Rick thinks this is perfect square trinomial. Tom thinks this is a difference of two squares because the first term is negative. Who is correct? Why or why not? –9x2 – 30x – 25 1c)...

Part A Solving 3x^2+7x−4=0 by completing the square method produces an equation of the form (x+h)^2=k. Find h and k. B.The equation x^2+2x−15=0 has two solutions A and B where A<B.
EXAMPLE 2 Find sin$(7x) cos”7x) dx. SOLUTION We could convert cos?(7x) to 1 - sin?(7x), but we would be left with an expression in terms of sin(7x) with no extra cos(7x) factor. Instead, we separate a single sine factor and rewrite the remaining sin" (7x) factor in terms of cos(7x): sin'(7x) cos”(7x) = (sinº(7x))2 cos(7x) sin(7x) = (1 - Cos?(7x))2 cos?(7x) sin(7x). in (7x) cos?(7x) and ich is which? Substituting u = cos(7x), we have du = -sin (3x) X...
