Question

X=2,y=-3,z=-2,a=2,b=3
4xy²-3yz²+4x²z
What is the solution

Answer 1

the answer is attached

Answer 2

Answer:

76

Step-by-step explanation:

$given \\ x = 2 \\ y = - 3 \\ z = - 2 \\ a = 2 \\ b = 3$

solution:

To find:4xy²-3yz²+4x²z

$= 4 \times 2 \times ( - 3 ){}^{2} \\ = 8 \times 9 = 72$

$\\ 3 \times ( - 3) \times ( - 2) {}^{2} \\ = - 9 \times 4 \\ = - 36$

$4 \times (2) {}^{2} \times ( - 2) \\ = 4 \times 4 \times (- 2) \\ = - 32$

$4xy {}^{2} - 3yz {}^{2} + 4x {}^{2}z \\ = 72 - ( - 36) + ( - 32) \\ = 72 + 36 - 32 \\ = 76$
