Question

X square + X - 30 tell me anwer

Answer 1

Answer:

x²+ x -30

factorisation by splitting middle term

x²+6x-5x-30

x(x+6) - 5(x+6)

(x-5) (x+6)

therefore alpha will be 5

and beta will be -6

Answer 2

Answer:

x=108²

Step-by-step explanation:

given:x²+x-30

x²+x=30. (-30 side changing)

x³ =30. (x²+x¹ =x³)

x=√30³. (cube root)

x=√27000. (30×30= 900×30=27000)

x= 108². (108×108=27000) that means square root of 108²=27000)
