Answer:
a = ± 2.958
Explanation:
We have to solve the given single-variable quadratic equation of a for a.
The equation is
2a² = 17.5 {Since, there is no a terms, so we can solve it directly}
⇒ a² = 8.75 {Dividing both sides by 2}
⇒ a = ± √(8.75) {Square root each sides of the equation, and get}
⇒ a = ± 2.958 (Answer)
