Question

How to factor trinomial?

Answer 1

Answer:

(x+5)(X+9)

Step-by-step explanation:

This is a monic quadratic trinomial. you need to find the product, which is the first times the last (1x times 45 which just becomes 45) and the sum, which is the middle number (14)

you need to find factors that ADD to get 14 and MULTIPLY to get 45

which in this case is 9 and 5. you then put it into this form (x+  )(x+  )

and u put the numbers in each one

(x+5)(x+9)

i hope this was helpful, pls give me brainliest    

Answer 2

Answer:(x+5)(x+9)

Step-by-step explanation:

x^2+14x+45

We first find two numbers whose product is +45 and whose sum is 14.the two numbers are 9 and 5.we then remove +14x from the equation and replace it with +9x+5x

x^2+9x+5x+45

On factorising we get

x(x+9)+5(x+9)

We then factor out (x+9) again

(x+5)(x+9)
