Question

Which choice shows the expression 4x2 + 13x + 9 in factored form?

Answer 1

Answer:

4x²+13x+9

iwill give you good method to simplify this

firstable take the 4 from x² and multiply it by 9

x²+13x+36

we find this equation

so the values is 4 and 9 because 4+9=13

4×9=36

(x+ )×(x+ )

first we take 9 and devide it by 4

9/4 the four for the x and the nine is number

so its will be

(4x+9)×(x+ )

same thing with 4 devide by 4 so the value is 1

so its will be like this

(4x+9)×(x+1) and this is the answer hopefully you understand my explain with my English
