Answer 1

Answer:

(x+8)(x-3)

Step-by-step explanation:

4x^2+20x-96=0

x^2+5x-24

x^2+8x-3x-24

x(x+8)-3(x+8)

(x+8)(x-3)

Answer 2

Answer:

4x^2+20x-96

x^2+5x-24

a=l,b=5,c=-24

x=-b plus or minus √b^2-4ac/2a

x=-5 plus or minus√25+96/2

x=-5 plus or minus √l2l/2

x=-5 plus or minus ll/2

x=-5+ll/2 x=-5-ll/2

x=6/2=3 x=-l6/2=-8
