2×5^{2} if you don't understand its 2 times 5 to the second power.
Answer:
(-12, 2).
Step-by-step explanation:
x^2 + 10x = 24
Divide the + 10 by 2 to give the following identity:
x^2 + 10x is equivalent to (x + 5)^2 - 25 so:
(x + 5)^2 - 25 = 24
(x + 5)^2 = 49
Taking square roots:
x + 5 = +/- 7.
x = -5 + 7 = 2
and x = -5 - 7 = -12.
