Question

can somebody help me with this? Evaluate each polynomial for the given value of the variable. –x2-5x+6; x= -3

Answer 1

replace all the x's in the polynomial with -3 and work it out;-
-(-3)^2 - 5(-3) + 6 = ?
notice its best to put the -3 in parentheses

Answer 2

-5x means '-5 times x'
so -5(-3) means -5 times -3

Answer 3

how would I check my answer? is there a way or no

Answer 4

the answer is 30 @welshfella ?

Answer 5

9+15+6=30

Answer 6

-(-3)^2 - 5(-3) + 6 = -9 + 15 + 6 = -9 +12 = ?

Answer 7

isn't a negative times a negative a positive?

Answer 8

-2 * -3 = 9
but there's a - sign before the x^2

Answer 9

if the first term was (-x)^2 then it would be 9 but as its written its -x^2

Answer 10

im so confused sorry

Answer 11

-9 + 15 + 6 = -9 +12 = ? where did you get the 12?

Answer 12

oh sorry its 15 + 6 = 21

Answer 13

so that's -9 + 21

Answer 14

Answer 15
