How do you factor these equations?????

Question

1. x^2+5x+4 #2. x^2-6x+9 #3. 5x^2+12x+7 #4,. 16x^2-36

Answer 1

1. x^2+5x+4  = (x+1)(x+4)

#2. x^2-6x+9  = (x-3)(x-3)

#3. 5x^2+12x+7 = (5x  +1)(x + 7 )

#4,. 16x^2-36 = (4x-6)(4x+6)

Answer 2

1rst of all do u know how to solve them if i give u the answers. idk how to explain it but check these. once u F.O.I.L them u will c:

1. x^2+5x+4 ---> (x+4)(x+1)

2. x^2- 6x+9 ---> (x-3)(x-3)

3. if i am not mistaken #3 is already factored. nothing goes into seven exept 1 and 7

4. 16x^2-36 ---> its the difference of two squares ---> (4x+6)(4x-6)
