Step-by-step explanation:

so question is x²-3x-28=0

x²-7x+4x-28=0

x(x-7)+4(x-7)

taking x-7 common we get

(x-7)(x+4)=0

hence x=7,-4

pls mark as brainliest

Answer 2

Answer:

with help of Middle term splitting method u can solve it easily

Step-by-step explanation:

x²-3x-28

first of all do factor of the Last term such that its difference will be equal to middle term

so

0 = x²-7x+4x-28

0 = x(x-7)+ 4(x-7)

0 =(x+4)(x-7)

x+3 = 0 , x-7=0

x = -4 and x = 7
