If (p(x)=x+2s) and (q(x)=x-3s), what is (p(x)+q(x))?
A. (2x-s)
जोड़ने पर (x+2s+x-3s=2x-s) मिलता है। (s) वाले पदों को भी समान पद की तरह मिलाएं। / On adding, (x+2s+x-3s=2x-s). Combine the (s)-terms like like terms.

If (p(x)=x+2s) and (q(x)=x-3s), what type of polynomial is (p(x)-q(x))?
B. नियतांक बहुपदConstant polynomial
(p(x)-q(x)=5s) है। (x) के संदर्भ में यह नियतांक बहुपद है। / (p(x)-q(x)=5s). With respect to (x), it is a constant polynomial.

For which value will the zero of ((n-3)x+2n+1) be (1)?
A. \(n=\frac{2}{3}\)
शून्यक (1) होने पर (n-3+2n+1=0) होगा। इससे (3n-2=0) और \(n=\frac{2}{3}\) मिलता है। / If the zero is (1), then (n-3+2n+1=0). Thus (3n-2=0) and \(n=\frac{2}{3}\).

If (p(x)=\frac{x}{5}+a) and (p(15)=11), what is the value of (a)?
B. (8)
(p(15)=3+a=11) से (a=8) मिलता है। भिन्न रूप में पहले (x) का मान रखें। / From (p(15)=3+a=11), we get (a=8). In fractional form, substitute the value of (x) first.

If (p(x)=4x+a) and (q(x)=x-6), what is (a) if the zero of (p(x)+q(x)) is (2)?
A. (-4)
(p(x)+q(x)=5x+a-6) है। (x=2) रखने पर (10+a-6=0) से (a=-4) मिलता है। / (p(x)+q(x)=5x+a-6). Substituting (x=2) gives (10+a-6=0), so (a=-4).

For which value will the zero of (p(x)=(c+4)x+2c) be (-2)?
A. कोई मान नहींNo value
(-2(c+4)+2c=0) से (-8=0) जैसा असंभव परिणाम मिलता है। इसलिए कोई मान नहीं है। / From (-2(c+4)+2c=0), we get the impossible result (-8=0). Therefore there is no value.

If the zero of (p(x)=(c+4)x+2c) is (-1), what is the correct value of (c)?
A. (c=4)
(-(c+4)+2c=0) से (c-4=0) मिलता है। अतः (c=4) है। / From (-(c+4)+2c=0), we get (c-4=0). Hence (c=4).

If (p(x)=rx+3) and (p(4)=23), what is the value of (p(-2))?
B. (-7)
(4r+3=23) से (r=5) मिलता है। इसलिए (p(-2)=5(-2)+3=-7) है। / From (4r+3=23), we get (r=5). Therefore (p(-2)=5(-2)+3=-7).
