what is y = (x + 3)2 + (x + 4)2 rewritten in vertex form?

Question

immideate answer asap please

Answer 1

y = (x + 3)² + (x + 4)²                      General forms

y = x² + 6x + 9 + x² + 8x + 16          combine

y = 2x² + 14x + 25                            complete the square

y = 2(x² + 7x + (7/2)²) + 25 - 49/2

y = 2(x + 3.5)² + 0.5
