Question

Solve the following quadratic for its zeros X2+ 16x + 71
X?

Answer 1

x = 0 or x = -87

Explanation:

Solve for x:

x^2 + 87 x = 0

Hint: | Factor the left hand side.

Factor x from the left hand side:

x (x + 87) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

x = 0 or x + 87 = 0

Hint: | Look at the second equation: Solve for x.

Subtract 87 from both sides:

Answer: x = 0 or x = -87
