Question

1)x^2=-x 2)-16-2(3-4x)=-3+8

Answer 1

1. x^2+x=0
x(x+1)=0
x=0, или х+1=0
х=-1

2. -16-6+12х=5
12х=27
х=27÷12
х=2.25

Answer 2

1. To solve the equation x^2 = -x, we can begin by bringing all terms to one side and then factoring out x:

x^2 + x = 0 x(x + 1) = 0

So, the solutions are x = 0 and x = -1.

2. To solve the equation -16 - 2(3 - 4x) = -3 + 8, we can simplify the left-hand side first by distributing the negative sign and the 2:

-16 - 6 + 8x = 5

Then, we can simplify further by combining like terms:

8x - 21 = 0

Finally, we can solve for x by adding 21 to both sides and then dividing by 8:

x = 21/8.
