What is the coefficients of x² in (2-3x) (x²-5)

aniked [119]

Answer:

Step-by-step explanation:

=> $(2-3x)(x^2-5)$

=> $(2x^2-10-3x^3+15x)$

Arranging it in descending order

=> $-3x^2+2x^2+15x-10$

So, the coefficient of x² in this expression is +2

What are the solutions to the system of equations? y=x2−7x+12y=−x+7

kap26 [50]

Answer:

x = 1, y = 6

x = 5, y = 2.

Step-by-step explanation:

y=x2−7x+12

y=−x+7

Substitute for y in the first equation:

- x + 7 = x^2 - 7x + 12

x^2 - 7x + x + 12 - 7 = 0

x^2 - 6x + 5 = 0

(x - 1)(x - 5) = 0

x = 1, 5.

When x = 1, y = -1 + 7 = 6.

when x = 5, y = -5+7 = 2.
