What is obtained by subtracting \(3a^2-9ab+2b^2\) from \(7a^2-4ab+6b^2\)?
A. \(4a^2+5ab+4b^2\)
घटाने पर \(7a^2-4ab+6b^2-3a^2+9ab-2b^2\) मिलता है। सरल रूप \(4a^2+5ab+4b^2\) है। / Subtraction gives \(7a^2-4ab+6b^2-3a^2+9ab-2b^2\). The simplified form is \(4a^2+5ab+4b^2\).

What is obtained after simplifying (3a-2-2ab+5b-2-\(2a^2+ab-4b^2\))?
C. \(a^2-3ab+9b^2\)
घटाने वाले कोष्ठक के चिन्ह बदलते हैं। सरल रूप \(3a^2-2ab+5b^2-2a^2-ab+4b^2=a^2-3ab+9b^2\) है। / Signs change in the subtracted bracket. The simplified form is \(3a^2-2ab+5b^2-2a^2-ab+4b^2=a^2-3ab+9b^2\).

Which expression is obtained by adding \(-x^2+5xy-4y^2\) to \(2x^2-3xy+y^2\)?
A. \(x^2+2xy-3y^2\)
समान पद जोड़ने पर \(2x^2-x^2=x^2\), (-3xy+5xy=2xy), और \(y^2-4y^2=-3y^2\)। / Adding like terms gives \(2x^2-x^2=x^2\), (-3xy+5xy=2xy), and \(y^2-4y^2=-3y^2\).
