Question

What is the answer in simplest form and is it real or imaginary?

Answer 1

12.292 or 1.708

Explanation:

1#60 - (2 • (x + 7)2 + 4) = 0

2# -2x2 - 28x - 42 = -2 • (x2 + 14x + 21)

3#x2 + 14x + 21 = -2 • (x2 + 14x + 21) = 0

Answer 2

`\\ \sf\longmapsto -60=2(h+7)^2+4`

`\\ \sf\longmapsto 2(h^2+14h+49)=-64`

`\\ \sf\longmapsto h^2+14h+49=-66`

`\\ \sf\longmapsto h^2+14h+115=0`

• h has imaginary roots
