Question

Find the value of :
a) 8x + 2y - 3xy +1 /2x^2 for x = - 3, y = 5

b) 4x^4 + x^3 + xy^2 - y^3 + 6 for x = - 2, y = 5​

Answer 1

Answer:

Answer=>

a)-1061/18

b)-176

Step-by-step explanation:

a) 8x + 2y - 3xy +1 /2x^2 for x = - 3, y = 5

x = - 3, y = 5

8(-3)+2(5)-3(-3)(5)+1/2(-3)^2

-24+10-45+1/18

=10-69+1/18

=-59+1/18

=>-1061/18.

b) 4x^4 + x^3 + xy^2 - y^3 + 6 for x = - 2, y = 5

x = - 2, y = 5

4(-2)^4+(-2)^3+(-2)(5)^2-(5)^3+6

4(16)-8-50-125+6

64-183+6

70-183

-176.
