need this for my homework, URGENTLY!!!
Find the value of 2a^2 + 5b^2 when a =-6 and b =2

Answer 1

$2a {}^{2} + 5b{}^{2}$

Substituting the values of a and b, we get :-

$= 2( - 6) {}^{2} + 5(2) {}^{2}$

$= 2 \times 36 + 5 \times 4$

$= 72 + 20$

$=92 \: \: ans$

Answer 2

HEY DEAR_______❤️❤️❤️❤️❤️❤️
HERE IS THE SOLUTION:-)
=>2a^2 + 5b^2

=>value of a = -6 and b = 2

PUT THE VALUE OF a AND b in the polynomial

=>2 x (-6)^2 + 5 x (2)^2

=>2 x 36 + 5 x 4

=>72 + 20

=>92
