Question

Solve by using formul
a :
x ( x + 1) = 6x + 24.​

Answer 1

Answer:

x2 + 2x + 1 – 2x + 6 = 0. ⇒ x2 + 70. Since x2 + 7 is a quadratic polynomial. ∴ (x + 1)2 = 2 (x – 3) is a ... 480u – 480u + 3840 = 3u2 – 24u ... The given equation has equal roots.

Answer 2

Answer:

x(x+1)=6x+24

x²+x=6x+24

x²+x-6x-24=0

x²-5x-24=0(By factorization method)

x²-8x+3x-24=0

x(x-8)+3(x-8)=0

(x+3)(x-8)=0

x+3=0. x-8=0

x=-3. x=8
