Question

factor trinomials where a =1

 

 

x² +14xy+45y²

 

Please show steps thanks much

Answer 1

1-Question what 2 numbers, multiplied = 45,

and when added = 14. The results are 9 and 5.

These will be the coefficients of the y term.

2-Since x² is the first term, x will be the first

term in each of the binominials.

3-Since y² is the last term, it will be the last

term in the binomials.

4-Since all signs in the trinomial are +, they

will be in the binomials.

5-Putting all together, you get:

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