Consider the vector space p2 of all polynomials of degree at most 2. find all real numbers a such that t^2 −at + 1−a^2 is in the span of t^2 −2t + 1, t−1 and 3t^2 −2t−1.
a. a can be any real number.
b. a = ±2.
c. a = −1 or a = 2.
d. a = −2 or a = 1.
e. a = 0.

the answer is 5/3x+7/5y+7

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
