Question

if a= 2 b = 3 ,c=1 evaluate -6 a2+ 5ab2+2bc2​

Answer 1

Answer:

48

Step-by-step explanation:

We plug in the values to get -6(2)2+5(2)(3)2+2(3)(1)2. Now we can multiply to get -24+60+12. We can combine like terms to arrive at our answer : 48.

Answer 2

Answer:

➡ Given,

➡ a = 2 , b = 3 , and c = 1

➡ Substituting the value of a, b and c, we get :

$- 6 {a}^{2} + 5a {b}^{2} + 2b {c}^{2} \\ \\ = - 6 {(2)}^{2} + 5(2) {(3)}^{2} + 2(3) {(1)}^{2} \\ \\ = - 6 \times 4 + 5(2) \times 9 + 2 \times 3 \times 1\\ \\ = - 24 + 90 + 6 \\ \\ = 66 + 6 \\ \\ = 72$
