Question

4. The product of two consecutive multiples of ‘2’ is 624. Then the numbers are –

Answer 1

Answer:

24,26 or -24,-26

Step-by-step explanation:

let the nos be 2x and 2x+2

ATQ,

2x*(2x+2) =624

4x^2 + 4x=624

x^2+x=156

x^2+x-156=0

x^2 +13x-12x-156=0

x(x+13)-12(x+13)=0

(x-12)(x+13)=0

x=12. x=-13

nos=2x, 2x+2

1st case. (x=12)

2x=24 , 2x+2 = 26

2nd case (x=-13)

2x=-26, 2x+2=-24
