Question

2 x square + x - 1 find the factor of the polynomial​

Answer 1

Answer:

The factors of 2x² + x - 1 is (2x - 1) and (x + 1)

Step-by-step explanation:

We are given,

2x² + x - 1 = 0

ax² + bx + c = 0

where a = 2, b = 1, c = -1

By Splitting the middle term method,

Sum = b = 1

Product = a × c = -2

Thus, factors are 2 and -1

2x² + x - 1 = 0

2x² + 2x - x - 1 = 0

2x(x + 1) -1(x + 1) = 0

(2x - 1)(x + 1) = 0

Thus, the factors of 2x² + x - 1 is (2x - 1) and

(x + 1)
