Answer:

first, subtract 17 on both sides: x²+2x-16=0

this cannot be factored, so use the quadratic formula to solve for x:

b²-4ac=2²-4(10(-16)=4+64=68

√68=2√17

so x=(-2+2√17)/2 or x=(-2-2√17)/2

x=-1+√17 or x=-1-√17

(6×5) + (6×2) = 6×7

It works if you think about it like this:
5 sixes + 2 sixes = (5 + 2) sixes = 7 sixes

This is an example of the <em>distributive property</em>.
To put it simply, we're applying the same multiplication (×6) to two different things which are being added together (5+2).

Here's another example of the distributive property:
2×(3+4) = 2×3 + 2×4
