The lens equation is 1/f=1/p+1/q , where f is the focal length of the lens, p is the distance of the object from the lens, and q is the distance of the image from the lens. the formula to find q is:
a. q=pf/p-f
b. q=p-f/pf
c. q=pf/p+f

Step-by-step explanation:

The lens equation is .

To solve this formula for , we need to multiply each term by .

.

We cancel out the common factors to get;

.

We group the terms in q on one side of the equation;

.

Factor q.

.

Divide both sides by

The correct answer is A

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
