After simplifying (5(2x-3)-3(3x+1)), which polynomial is obtained?
A. (x-18)
(10x-15-9x-3=x-18) है। कोष्ठक खोलने के बाद समान पद मिलाएं। / (10x-15-9x-3=x-18). After opening brackets, combine like terms.

For which value will (\(a^2-16\)x+7) not remain a linear polynomial?
B. (a=4) या (a=-4)(a=4) or (a=-4)
रेखीय न रहने के लिए (x) का गुणांक (0) होना चाहिए। \(a^2-16=0\) से \(a=\pm4\) मिलता है। / For it not to be linear, the coefficient of (x) must be (0). From \(a^2-16=0\), \(a=\pm4\).

If the zero of (p(x)=(k-2)x+9) is (-3), what is the value of (k)?
A. (5)
(-3(k-2)+9=0) से (k=5) मिलता है। शून्यक को बहुपद में रखकर (0) करें। / From (-3(k-2)+9=0), we get (k=5). Substitute the zero into the polynomial and set it to (0).

If (p(x)=3x-2) and (q(x)=x+5), what is (2p(x)-3q(x))?
A. (3x-19)
(2(3x-2)-3(x+5)=3x-19) है। गुणा करके समान पदों को मिलाएं। / (2(3x-2)-3(x+5)=3x-19). Multiply and then combine like terms.

For which value will the zero of ((2m-5)x+10) be (4)?
B. \(m=\frac{5}{4}\)
शून्यक (4) होने पर (4(2m-5)+10=0) होगा। इससे \(m=\frac{5}{4}\) मिलता है। / If the zero is (4), then (4(2m-5)+10=0). This gives \(m=\frac{5}{4}\).

If the zero of (p(x)=ax+b) is (2) and (a=5), what is (b)?
B. (-10)
(p(2)=0) से (2a+b=0) होगा। (a=5) रखने पर (b=-10) मिलता है। / From (p(2)=0), (2a+b=0). Substituting (a=5) gives (b=-10).

In which option is the sum of two linear polynomials the zero polynomial?
C. (5x-7) और (-5x+7)(5x-7) and (-5x+7)
(5x-7+(-5x+7)=0) है। विपरीत बहुपदों का योग शून्य बहुपद होता है। / (5x-7+(-5x+7)=0). The sum of opposite polynomials is the zero polynomial.

If (p(x)=4x+c) and (p(3)=p(1)+10), what is correct about (c)?
C. ऐसा कोई (c) नहींNo such (c)
(p(3)-p(1)=(12+c)-(4+c)=8) होता है। इसलिए (10) वाली शर्त किसी (c) पर पूरी नहीं होती। / (p(3)-p(1)=(12+c)-(4+c)=8). So the condition with (10) is not satisfied for any (c).

Which option has zero \(-\frac{3}{7}\) for a linear polynomial?
C. (7x+3)
(7x+3=0) से \(x=-\frac{3}{7}\) मिलता है। भिन्न शून्यक में चिन्ह और हर ध्यान रखें। / From (7x+3=0), we get \(x=-\frac{3}{7}\). Pay attention to the sign and denominator in fractional zeros.

If (p(x)=\frac{2}{5}x-6), for which value will (p(x)=0)?
C. (x=15)
\(\frac{2}{5}x-6=0\) से \(\frac{2}{5}x=6\) और (x=15) मिलता है। भिन्न गुणांक में उलटा गुणा करें। / From \(\frac{2}{5}x-6=0\), \(\frac{2}{5}x=6\) and (x=15). With a fractional coefficient, multiply by the reciprocal.
