Question

2x^2 + 13 + 20

i need help factorizing

Answer 1

ahh now you're clear.

first break down the middle term
\[\implies 2x^2 + 8x + 5x + 20\]
does that help?

Answer 2

not really because i dont get how you got the 8 and 5

Answer 3

8x + 5x = 13x

Answer 4

i just split the original 13x into two addends

Answer 5

ok.... here is a simple method using the coefficients ax^2 + bx + c

start with a x c

multiply the 2 and the 20

2 x 20 = 40

Answer 6

find the factors of 40 that add to 13

they are 8 and 5

then write it as



the 1st set of brackets has a common factor of 2

so put it outside



cancel out the 2 for the solution



hope it helps
