After simplifying (8(2x-1)-3(5x+4)), which linear polynomial is obtained?
A. (x-20)
(16x-8-15x-12=x-20) है। कोष्ठक खोलने के बाद समान पद मिलाएं। / (16x-8-15x-12=x-20). After opening brackets, combine like terms.

For which value will (\(v^2-36\)x-13) not remain a linear polynomial?
B. (v=6) या (v=-6)(v=6) or (v=-6)
रेखीय न रहने के लिए (x) का गुणांक (0) होना चाहिए। \(v^2-36=0\) से \(v=\pm6\) मिलता है। / For it not to be linear, the coefficient of (x) must be (0). From \(v^2-36=0\), \(v=\pm6\).

If the zero of (p(x)=(k-6)x+18) is (-3), what is (k)?
C. (12)
(-3(k-6)+18=0) से (k=12) मिलता है। शून्यक को बहुपद में रखकर समीकरण बनाएं। / From (-3(k-6)+18=0), we get (k=12). Substitute the zero into the polynomial to form the equation.

If (p(x)=8x-5) and (q(x)=3x+11), what is (2p(x)-5q(x))?
A. (x-65)
(2(8x-5)-5(3x+11)=x-65) है। पहले गुणा करें फिर समान पद मिलाएं। / (2(8x-5)-5(3x+11)=x-65). Multiply first and then combine like terms.

For which value will the zero of ((4a-5)x+30) be (-2)?
A. (a=5)
शून्यक (-2) होने पर (-2(4a-5)+30=0) होगा। इससे (a=5) मिलता है। / If the zero is (-2), then (-2(4a-5)+30=0). This gives (a=5).

If the zero of (p(x)=ax+b) is (7) and (a=-4), what is (b)?
C. (28)
(p(7)=0) से (7a+b=0) होगा। (a=-4) रखने पर (b=28) मिलता है। / From (p(7)=0), (7a+b=0). Substituting (a=-4) gives (b=28).

If (p(x)=11x+c) and (p(4)=p(1)+33), what is correct about (c)?
B. हर (c) सही हैEvery (c) is valid
(p(4)-p(1)=(44+c)-(11+c)=33) है। इसलिए शर्त हर (c) के लिए सही है। / (p(4)-p(1)=(44+c)-(11+c)=33). So the condition is true for every (c).

Which option has zero \(-\frac{9}{13}\) for a linear polynomial?
C. (13x+9)
(13x+9=0) से \(x=-\frac{9}{13}\) मिलता है। भिन्न शून्यक में चिन्ह और हर ध्यान रखें। / From (13x+9=0), we get \(x=-\frac{9}{13}\). Pay attention to the sign and denominator in fractional zeros.

If (p(x)=\frac{8}{15}x-16), for which value will (p(x)=0)?
C. (x=30)
\(\frac{8}{15}x-16=0\) से \(\frac{8}{15}x=16\) और (x=30) मिलता है। भिन्न गुणांक में उलटा गुणा करें। / From \(\frac{8}{15}x-16=0\), \(\frac{8}{15}x=16\) and (x=30). With a fractional coefficient, multiply by the reciprocal.

If (p(x)=x-10) and (q(x)=x+3), what is the degree of (p(x)q(x))?
B. (2)
((x-10)(x+3)) में उच्चतम पद \(x^2\) है। इसलिए गुणनफल की डिग्री (2) है। / In ((x-10)(x+3)), the highest term is \(x^2\). Therefore the product has degree (2).
