Answer:

(m − 3) (m + 2)

Step-by-step explanation:

m² − m − 6

To factor a quadratic ax² + bx + c, you can use the AC method.

1. Multiply a and c.

2. Find factors of ac that add up to b.

3. Divide the factors by a and reduce.

4. The denominators are the coefficients, the numerators are the constants.

Here, a = 1, b = -1, and c = -6.

1. ac = -6

2. Factors of -6 that add up to -1 are -3 and 2.

3. -3/1, 2/1

4. Factors are m − 3 and m + 2.

m² − m − 6 = (m − 3) (m + 2)

What is the volume of the cylinder if the height is 2x+7 and the radius is x-3
shusha [124]

Answer:

Therefore the volume of the cylinder=\pi(2x^3-5x^2-24x+63)  cubic units

Step-by-step explanation:

Given height of a cylinder is (h) =2x+7

and radius  (r)= x-3

Volume of the cylinder = \pi r^2 h

                                  =\pi (x-3)^2(2x+7)

                                  =\pi (x^2-6x+9)(2x+7)

                                  =\pi (2x^3-12x^2+18x+7x^2-42x+63)

                                  =\pi(2x^3-5x^2-24x+63)  cubic units

Therefore the volume of the cylinder=\pi(2x^3-5x^2-24x+63)  cubic units
