Step-by-step explanation:
Solution Steps
4(2x−1) 2 +12(2x−1)+9
Use binomial theorem (a−b) 2 =a 2 −2ab+b 2 to expand (2x−1) 2
4(4x 2 −4x+1)+12(2x−1)+9
Use the distributive property to multiply 4 by 4x 2 −4x+1.
16x 2 −16x+4+12(2x−1)+9
Use the distributive property to multiply 12 by 2x−1.
16x 2 −16x+4+24x−12+9
Combine −16x and 24x to get 8x.
16x 2 +8x+4−12+9
Subtract 12 from 4 to get −8.
16x 2 +8x−8+9
Add −8 and 9 to get 1.
16x 2 +8x+1
SOLUTION STEPS
2(x−y) 2 −3(x−y)−9
Use binomial theorem (a−b) 2 =a −2ab+b 2 to expand (x−y) 2 .
2(x 2 −2xy+y 2 )−3(x−y)−9
Use the distributive property to multiply 2 by x 2 −2xy+y 2 .
2x 2 −4xy+2y 2 −3(x−y)−9
Use the distributive property to multiply −3 by x−y
. 2x 2 −4xy+2y 2 −3x+3y−9
