Question

(3) If the value of the polynomial m^2 + 2m + a is 12 for m = 2, then find the value of a.

(4) For the polynomial mx^2
2x + 3 if p(- 1) = 7 then find m.

don't give irrelevant answers it will be reported.​

Answer 1

Answer:

3 ) Given :

m^3 + 2m + a = 12, where m = 2.

Therefore,

m^3 + 2m + a = 12

2^3 + 2×2 + a = 12

8 + 4 + a = 12

a = 0.

4) Given polynomial mx^2-2x+3mx

2

−2x+3

we have to find the value of m if p(-1)=7 then find m ..

p(x)=mx^2-2x+3p(x)=mx

2

−2x+3

p(-1)=m(-1)^2-2(-1)+3p(−1)=m(−1)

2

−2(−1)+3

7=m+2+37=m+2+3

m=2m=2
