Answer:
1. f^2-7f+12 = (f-3)(f-4)
2. x^2+15x+56 = (x+7)(x+8)
3. u^2-2u-27 = Cannot factor
4. x^2-6x+7 = Cannot factor
5. v^2+8v+9 = (v+9)(v-1)
6. 2x^2-4x+1 = Cannot factor
Step-by-step explanation:
In numbers, 3, 4, and 6. The answer is cannot factor because there is no GCF.
1. f^2-7f+12
Finding the answer of -7f
(-3f)+(-4f) = -7f
(+4f)+(+3f) = +7f
(-6f)+(-2f) = -8f
(+2f)+(+6f) = +8f
so the answer of -7f are -3 and -4
Final answer: (f-3)(f-4)
2. x^2+15x+56
Finding the answer of +15x
(-7x)+(-8x) = -15x
(+7x)+(+8x) = +15x
(-5x)+(-3x) = -8x
(+5x)+(+3x) = +8x
so the answer of +15x are 7 and 8
Final answer: (x+7)(x+8)
5. v^2+8v+9
Finding the answer of +8v
(-9v)+(v) = -8v
(+9v)+(-1v) = +8v
(-3v)+(-3v) = -6v
(+3v)+(+3v) = +6v
so the answer of +8v are 9 and 1
Final answer: (v+9)(v-1)
