Use the following method in the example to write as a product of two integers.

Example:

Since the coefficient of is 2, then all we have to do is find two numbers that multiply to be and add to be .
Those numbers are 2 and 1.

Let's factor by grouping.

Other notes:
You will still be factoring a quadratic. However, one of your coefficients might be a double digit-ed number.

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
