Question

Simplify the expression and find its value when a = 5 and b = -3 .

Answer 1

Answer:

$\sf\longmapsto \: 38$

Step by step explanation:

$\sf\longmapsto \: 2a² + 2ab +3-ab$

$\sf\longmapsto \: 2a² + 3 + ab (2-1)$

$\sf\longmapsto \: 2a² + 3 + ab (1)$

$\sf\longmapsto \: 2a² + 3 + ab$

$\sf\longmapsto \: 2a² + ab + 3$

• Putting a = 5 b = - 3

$\sf\longmapsto \: 2(5) {}^{2} + (5) (-3) +3$

$\sf\longmapsto \: 2 (25) - 15 + 3$

$\sf\longmapsto \: 50 - 12$

$\sf\longmapsto \: 38$
