Question

Factor the expression.

4x² + 25x + 36

Answer 1

(x+4)(4x+9)

Answer 2

How did you get that?

Answer 3

find the roots
name them by x1, x2
ax^2+bx+c =a(x-x1)(x-x2)

Answer 4

like this
x^2-4x+3
x1,x2 = 1,3
so
x^2-4x+3 =(x-1)(x-4)
or
this
4x^2-3x-1
x1,x2=1,-1/4
so
4x^2-3x-1 =4 (x-1) (x-(-1/4)
=(x-1)(4x+1)

Answer 5

can you find the roots of 4x² + 25x + 36=0 ?

Answer 6

Yup I can take it from there thanks :)
