Hey mate here's your answer
15. a) This is not a linear equation as the highest power of variable is 2
b) This is not a linear equation as they are never in fraction.
c) (x+2)^2 = x^2 + 16
x^2 + 4 + 4x = x^2 + 16
4x= 12
x= 3
This is a linear equation
d) ( x-2) (x+5)= x+14
x^2 + 5x - 2x - 10 = x+ 14
x^2 - x + 3x - 14 = 0
x^ 2 + 2x - 14 = 0
This is also not a linear equation
16. Given √5= 2.236
1 - √5/3 - 2√5
1 - 2.236/3 - 2 x 2.236
-1.236/-1.472
0.836
17.(3√5-5√2)(4√5+3√2)
=3√5*4√5+3√5*3√2-
5√2*4√5-5√2*3√2
=60+9√10-20√10-60
= -19√10
Hope it helps you
