Question

(5x-1)(5x-1) + (3x+4)(3x+4)

Answer 1

34x^2 +14x+17

Explanation:

(25x^2 - 10x +1) + (9x^2 + 24x + 16)

= 34x^2 +14x+17

Answer 2

=34x2+14x+17

Explanation:

=(5x)(5x)+(5x)(−1)+(−1)(5x)+(−1)(−1)+(3x)(3x)+(3x)(4)+(4)(3x)+(4)(4)

=25x2+−5x+−5x+1+9x2+12x+12x+16

Combine Like Terms:

=25x2+−5x+−5x+1+9x2+12x+12x+16

=(25x2+9x2)+(−5x+−5x+12x+12x)+(1+16)

=34x2+14x+17
