Question

Find the real roots of the equation 2^2x^2-7x+5=1​

Answer 1

Step-by-step explanation:

This is the answer

Simplifying

2x2 + 7x + -5 = -1

Reorder the terms:

-5 + 7x + 2x2 = -1

Solving

-5 + 7x + 2x2 = -1

Solving for variable 'x'.

Reorder the terms:

-5 + 1 + 7x + 2x2 = -1 + 1

Combine like terms: -5 + 1 = -4

-4 + 7x + 2x2 = -1 + 1

Combine like terms: -1 + 1 = 0

-4 + 7x + 2x2 = 0

Factor a trinomial.

(-4 + -1x)(1 + -2x) = 0
