Factor the following
x^2+3x+2
x^2+15x+50

1)

2)

Step-by-step explanation:

You can factorize the quadratics equations by applying the proccedure shown below:

1)

Find two number whose sum is 3 and whose product is 2.

These would be 1 and 2.

Rewrite it as folowing:

 2)

Find two number whose sum is 15 and whose product is 50.

These would be 5 and 10.

Therefore, you can rewrite it as folowing:

here is your mark brainliest

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
