17. (x^2-x+3)(4x+1)
18.(x+2)(x) - (7)(3)
This is a parabola which opens upwards
y - (-3) = sqrt ((y+1)^2 + (x + 5)^2
(y + 3)^2 = y^2 + 2y + 1 + (x + 5)^2
y^2 + 6y + 9 = y^2 + 2y + 1 + (x + 5)^2
(x + 5)^2 = 4y + 8
(x + 5)^2 = 4(y + 2)
Its C
Answer:
(4x+5) (16x^2- 20x +25)
Step-by-step explanation:
Since both terms are perfect cubes, factor using the sum of cubes formula.
Cubes Formula:
a^3+b^3=(a+b)(a^2−ab+b^2)
where a=4x and b=5.
hence, why the answer is (4x+5) (16x^2- 20x +25)
