Find ? a, b), iai, ibi, and d(a, b) for the matrices in m2.2 using the inner product (a, b) = 2a11b11 + a21b21 + a12b12 + 2a22b22 a=[ 2-5] (a) a, b , b=1-21 1 0 -1 4 (b) all (c) ißll (d) d(a, b)

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
