✰Answer:
9x^2 + 2x + 8.
✰
Step-by-step explanation:
To simplify the expression (2x^2 + 5x + 3) − (−7x^2 + 3x - 5) and write it in standard form, we need to combine like terms.
Step 1: Distribute the negative sign to the terms in the second set of parentheses. This gives us:
(2x^2 + 5x + 3) + (7x^2 - 3x + 5)
Step 2: Combine like terms. Add the coefficients of the terms with the same degree of x. We get:
(2x^2 + 7x^2) + (5x - 3x) + (3 + 5)
Simplifying further, we have:
9x^2 + 2x + 8
So, the simplified expression in standard form is 9x^2 + 2x + 8.
