Find the value of 2a² + 5b² when a= -6 and b= 2

2(-6^2)+5(2^2)
2(36)+5(4)
72+20
92

Plug in the values -6 into 'a' and 2 into 'b'. 

2a² + 5b² 
2(-6)² + 5(2)²
First solve the exponents  ⇒  -6² means -6 * -6, which equals 36
2² = 2*2 = 4

2(36) + 5(4)
2*36 → 72
5*4 = 20
72 + 20 = 92  

Final answer → 92
