Answer:
(3x + 1)²
Step-by-step explanation:
Given
9x² + 6x + 1 ← is a perfect square of the form
(ax + b)² = a²x² + 2abx + b²
Compare like terms to find a and b
a²x² = 9x² ⇒ a² = 9 ⇒ a = = 3
b² = 1 ⇒ b = = 1
and 2ab = 2 × 3 × 1 = 6
Thus
9x² + 6x + 1 = (3x + 1)²
Answer:
The slope is .
Step-by-step explanation:
The equation is conveniently in slope-intercept form.
m - slope
b - y-intercept
-2/3 is in m's spot, so it is the slope of the equation.
Hope this helps.
