Question

: Express the quadratic equation 7x^2 + 6x - 4 = 5x^ in standard form.

a) 7x^2 + x - 4 = 0
b) 2x^2 + 6x + 4 = 0
c) 7x^2 - x + 4 = 0
d) 7x^2 + x + 4 = 0

Answer 1

To express the quadratic equation 7x^2 + 6x - 4 = 5x^ in standard form, the correct answer is option a) 7x^2 + x - 4 = 0.

Step-by-step explanation:

To express the quadratic equation 7x^2 + 6x - 4 = 5x^ in standard form, we need to rearrange it so that the highest power of x is on the left side and all the terms are arranged in descending order of powers.

After rearranging, the equation becomes 7x^2 + x - 4 = 0. Therefore, the correct answer is option a) 7x^2 + x - 4 = 0.
