Evaluate each of the algaebraic expression for x=1 and y=-1 and z=2 and a =-2 and b=1 and c=-2
ax2+ by2 -cz2
Dear Student,
Ans. Given value of:
x = 1, y = -1, z = 2, a = -2, b = 1, c = -2
Using these values in the algebraic expression, we get:
ax² + by² - cz²
= {(-2) × 1²} + {1 × (-1)²} - {(-2) × 2²}
= { (-2) × 1} + { 1 × 1 } - { -2 × 4}
= (-2) + 1 - (-8)
= -2 + 1 + 8
= -2 + 9
= 7
Regards
