Answer:
{0, 4 and -3}
Step-by-step explanation:
f(x)=x^3-x^2-12x can be factored, starting by taking out the 'x' factor:
f(x)=x^3-x^2-12x = x(x^2 - x - 12), and then by factoring the quadratic:
f(x) = x(x - 4)(x + 3) = 0
Then the zeros are {0, 4 and -3}.
The first one:))) Hope you do well
The goal is to put the equation in the simplest form to solve:
2x²+17=179
Subtract both sides by 17.
179-17= 162
2x²=162
Square root 162.
√162 = 12.7 (rounded)
2x=12.7
Divide both sides by 2.
12.7/2= 6.4 (rounded)
x=6.4
The variable x is 6.4, rounded to the nearest tenth for simple purposes.
