2a squared is equal to 17.5. Solve for a

a = ± 2.958

Step-by-step 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)
