For how many integer values of p does the expression p × p + 4 × p - 3 have a negative value‘?

Answer 1

Answer:

-4,-3,-2,-1,0.

Step-by-step explanation:

 р²+4р-3<0

р²+4р-3=0 ,D=28 ,х₁=-2+√7 , х₂ =-2-√7.

+++++++(-2-√7)----------(-2+√7)++++++

√7≈2,64 , -2-√7 ≈ - 4,64 , -2+√7≈0,64.

р=-4 ,р=-3 ,р=-2 ,р=-1 ,р=0 .
