To simplify sqrt(28x) + sqrt(63x), you can first factor the numbers inside the square roots.
28x can be factored as 4 * 7 * x, and 63x can be factored as 9 * 7 * x.
Now, you can simplify the square roots by taking out the perfect square factors.
sqrt(28x) = sqrt(4 * 7 * x) = 2 * sqrt(7x) sqrt(63x) = sqrt(9 * 7 * x) = 3 * sqrt(7x)
Combining the simplified square roots, you get:
2 * sqrt(7x) + 3 * sqrt(7x) = (2 + 3) * sqrt(7x) = 5 * sqrt(7x)
Therefore, sqrt(28x) + sqrt(63x) simplifies to 5 * sqrt(7x).
