Answer:
1. x^2 - 2x - 8 = 0
2. x^2 - 1/4 = 0
3. x^2 - 4/3 x -5/4 = 0
4. x^2 - 5x - 14 = 0
5. x^2 + 20x + 51 = 0
1. x^2+2x-8=0
2.4x^2-1=0 (not sure)
3.x^2+ 4/3 - 5/4=0
4.x^2-5-14=0
5. x^2+20+51=0
Step-by-step explanation:
Sum is the middle term for it is acquired if the OI(uses addition/subtraction) in FOIL is used
Product is the last term (L in FOIL) for it is acquired by multiplying
Roots i.e.
The 7 and -2 are roots
No.5 answer is -3 for: -17 and -3 are roots therefore they are needed to be converted to 17 and 3 therefore; =

Step-by-step explanation:
Sum is the middle term for it is acquired if the OI(uses addition/subtraction) in FOIL is used
Product is the last term (L in FOIL) for it is acquired by multiplying
Roots i.e.![(x-7)(x+2)\\=x=7 ; x=-2 (x-7)(x+2)\\=x=7 ; x=-2](https://tex.z-dn.net/?f=%28x-7%29%28x%2B2%29%5C%5C%3Dx%3D7%20%3B%20x%3D-2)
The 7 and -2 are roots
No.5 answer is -3 for:
-17 and -3 are roots therefore they are needed to be converted to 17 and 3 therefore;
=![x^{2} +17x+3x+51= x^{2} +20x+51 x^{2} +17x+3x+51= x^{2} +20x+51](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B17x%2B3x%2B51%3D%20x%5E%7B2%7D%20%2B20x%2B51)
