Question

Write the following quadratic equations in standard form and determine the values of a, b and c.
Quadratic equation standard form a b c
1.(n+2)n=-7
2.5p=2p²-8
3.(×+2)(×-1)=4

Answer 1

Answer:

1. (n+2)n=-7

=⟩(n+2)n=-7

.'. n²+2n=-7

n²+2n+7=0 –Standard form

here a=1, b=+2, c=7

similarly carry out the approach for other sums
