Question

find it in to find the value of algebraic expression solve full in long ​

Answer 1

Answer:

(I) -4

(ii) 52

(iii) -1

(iv) 50

(v) -8

Step-by-step explanation:

(I)2a+3b-c if a=3 ,b= -4, c= -2

then,2(3)+3(-4)-(-2)

=6-12+2

=-4

(ii)a³+b³+c³-3abc if a= -1,b=2, c=3

then,(-1)³+(2)³+(3)³-3(-1)(2)(3)

= -1+8+27+18

= -1+53

=52

(iii)a³+b³+3ab²+3a²b if a=2,b= -3

then, (2)³+(-3)³+3(2((-3)²+3(2)²(-3(

=8-27+54-36

=62-63

= -1

(iv)5+a²+ab-9c if a=5,b=4,c=0

then,5+(5)²+5×4-9(0)

=5+25+20-0

=50

(v)6a²-5b²+2c²-3a²bc if a=1,b=2,c= -1

then,6(1)²-5(2)²+2(-1)²-3(1)²(2)(-1)

=6-20+2+6

= -6

I hope my answer is helpful for you.....
