Question

Graph of the polynomial p(x) =px² + 4x – 4 passes through point (2 , 0). The value of p is ___________​

Answer 1

Answer:

px2 + 4x - 4

p ×(2×2) + 4×2 - 4

p4 +8 -4

4p = 4

p = 1

Answer 2

Answer:

-1

Step-by-step explanation:

px²+4x-4=0

p(2)²+ 4(2) - 4 =0

p(4) + 8 - 4 = 0

4p + 4 = 0

4p = - 4

p = -4

4

p = - 1
