subtract (7x - 9) from (2x^{2}-11).\n(2x^{2}-7x - 20)\n(2x^{2}-7x - 2)\n(2x^{2}+7x - 20)\n(2x^{2}+7x - 2)

Explanation:

Step1: Write the subtraction expression

$(2x^{2}-11)-(7x - 9)$

Step2: Distribute the negative sign

$2x^{2}-11-7x + 9$

Step3: Combine like - terms

$2x^{2}-7x+(-11 + 9)=2x^{2}-7x - 2$

Answer:

$2x^{2}-7x - 2$ (corresponding to the second option)
