Question

factorisation method x*2 -3x - 28 = 0​

Answer 1

Answer:

Step-by-step explanation:

x² -3x - 28 = 0​

x²-7x+4x-28 = 0

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

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

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

x= 7 or x = -4

Answer 2

Answer:

Your answer is 7 or (-4).

Step-by-step explanation:

x*2 - 3x - 28 = 0

x*2 + 4x - 7x - 28 = 0

(x*2 + 4x) - ( 7x - 28) = 0

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

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

So, x-7=0 or x+4=0

So, x=7 or x=(-4).
