$f(x)=4x^2-3x+2kx+1=4x^2+(2k-3)x+1\n\na=4;\ b=2k-3;\ c=1\n\nfunction\ has\ two\ zeros\ when\ \Delta=b^2-4ac > 0\n\n\Delta=(2k-3)^2-4\cdot4\cdot1=4k^2-12k+9-16=4k^2-12k-7 > 0\n\na_k=4;\ b_k=-12;\ c_k=-7\n\n\Delta_k=(-12)^2-4\cdot4\cdot(-7)=144+112=256\n\nk_1=(-b_k-√(\Delta_k))/(2a_k);\ k_2=(-b_k+√(\Delta_k))/(2a_k)$

Berta determined that the solution is (–2, 3). Which could have been the equation Berta found in step 1? 4x = 0 5x = 10 5x = –10 5x = –25

Answers

The equation that Berta determined could be 5x = - 10.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Berta determined that the solution is (- 2, 3).

From the given options the only x-coordinate value satisfying is

5x = - 10.

As at x = - 2.

5(-2) = - 10.

- 10 = - 10.

The solution (- 2, 3) can also be called as an ordered pair.
