Write the trinomial in factored form (as the product of two binomials)
x^2 -3x -18

( x + 3 )(x - 6)

Step-by-step explanation:

if you factor x2−3x−18

x2−3x−18

The middle number is -3 and the last number is -18.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -3

Multiply together to get -18

Can you think of the two numbers?

Try 3 and -6:

3+-6 = -3

3*-6 = -18

Fill in the blanks in

(x+_)(x+_)

with 3 and -6 to get...

(x+3)(x-6)

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
