Y = -x2 + 5x + 36 <span>→ y = -(x2 -5x -36)
</span><span>→ y = -(x2 - 9x +4x - 36)
</span><span>→ y = -[x(x-9) + 4(x - 9)]
</span><span>→ y = -(x - 9)(x + 4)
Your answer would be </span>y=-(x-9)(x+4).
The m in the equation is the slope and the y-intercept is the b.
y=1x-1
y=mx+b
I would suggest factoring using the grouping method. The answer I got was (2n-1)(n+2)
