Question

3(5-2x)-x(-5+2x) x(5x-1)+11(-5x+1)

Answer 1

15- 6х+5х -2х

5хво втой степени -х-55х+11

Answer 2

To simplify the given expressions, follow the order of operations (PEMDAS/BODMAS):

1. Simplify the first expression: 3(5-2x) - x(-5+2x) Apply distributive property first, then combine like terms: = 3 * 5 - 3 * 2x - x * -5 + x * 2x = 15 - 6x + 5x - 2x^2 Combine like terms: = -2x^2 - x + 15

2. Simplify the second expression: x(5x-1) + 11(-5x+1) Apply distributive property first, then combine like terms: = x * 5x - x * 1 + 11 * -5x + 11 * 1 = 5x^2 - x - 55x + 11 Combine like terms: = 5x^2 - 56x + 11

So the simplified expressions are:

1. -2x^2 - x + 15
2. 5x^2 - 56x + 11
