What is the factorised form of \(a^2-b^2+3a+3b\)?
A. ((a+b)(a-b+3))
(a-2-b-2=(a-b)(a+b)) और (3a+3b=3(a+b)) है। परीक्षा में समान ((a+b)) बाहर लें। / (a-2-b-2=(a-b)(a+b)) and (3a+3b=3(a+b)). In exams, take common ((a+b)) outside.

Choose the correct factorisation of \(p^2-q^2-5p+5q\).
B. ((p-q)(p+q-5))
(p-2-q-2=(p-q)(p+q)) और (-5p+5q=-5(p-q)) है। परीक्षा में चिह्न सहित सामान्य ((p-q)) पहचानें। / (p-2-q-2=(p-q)(p+q)) and (-5p+5q=-5(p-q)). In exams, identify common ((p-q)) with signs.

What is obtained by factorising \(x^2-9+4x+12\)?
C. ((x+3)(x+7))
व्यंजक \(x^2+4x+3\) नहीं बल्कि \(x^2+4x+3\) है, इसलिए गुणनखंड ((x+1)(x+3)) होंगे। ध्यान दें कि दिए पदों को पहले सरल करें। / The expression simplifies to \(x^2+4x+3\), so the factors are ((x+1)(x+3)). First simplify the given terms carefully.

What is the factorised form of \(7x^2+29x+30\)?
A. ((7x+15)(x+2))
((7x+15)(x+2)) से \(7x^2+14x+15x+30\) मिलता है। परीक्षा में मध्य पदों का योग (29x) जाँचें। / ((7x+15)(x+2)) gives \(7x^2+14x+15x+30\). In exams, check that the middle terms add to (29x).

What will be the complete factorised form of \(12x^2-20xy+8y^2\)?
A. (4(3x-2y)(x-y))
पहले (4) सामान्य निकालें और (3x-2-5xy+2y-2=(3x-2y)(x-y)) है। परीक्षा में सामान्य गुणनखंड के बाद त्रिपद भी तोड़ें। / First take (4) common and (3x-2-5xy+2y-2=(3x-2y)(x-y)). In exams, factor the trinomial after the common factor.

Factorise \(x^2+5x+6-y^2-5y\).
A. ((x-y+2)(x+y+3))
इसे (\(x^2-y^2\)+5(x-y)+6) मानें और (u=x-y) रखें। परीक्षा में (x+y) वाला बचा पद ध्यान से रखें। / Treat it as (\(x^2-y^2\)+5(x-y)+6) and use (u=x-y). In exams, keep the remaining (x+y) term carefully.

What is the factorised and simplified form of ((x+y)2-(x-y)2)?
A. (4xy)
वर्गों के अंतर से ((2y)(2x)=4xy) मिलता है। परीक्षा में (\(A^2-B^2\)) को ((A-B)(A+B)) लिखें। / Using difference of squares gives ((2y)(2x)=4xy). In exams, write (\(A^2-B^2\)) as ((A-B)(A+B)).
