Question

Factorise. ; a2x2 + (ax3+1)x2 +a
Solve by elimination method 3x-7/2 -2y-8/3 = -1 and 5-x/3 - 3-2y/7 = 1
Solve by cross multiplication method :5/(x-1) + 1/(y-2) = 2 and 6/(x-1)- 3/(y-2) = 1

Answer 1

Answer:

Step-by-step explanation:

A^2*x^2+(ax^2+1)x+a

= a^2*x^2+ax^3+x+a

= a^2*x^2+a+ax^3+x

= a(ax^2 + 1) + x(ax^2 + x)

= (a+x)(ax^2+1)
