Answer:
2 + (-7) = (-5)
Step-by-step explanation:
Correct problem and method of solving, just miscounted!
It should be + (-7) instead of + (-6).
This also changes the answer to (-5) instead of (-4).
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
