Answer:
Step-by-step explanation:
2x+y=1---------> y=-2x+1
x-2y=3
2) x-2(-2x+1)=3
x+4x-2=3
5x=5
x=1
3) 2x+y=1 when x=1
2(1)+y=1
2+y=1
y=1
the answer is (1,1)
The factors of the trinomial to the given quadratic expression are (x+1) and (x-4)
<h3>Factoring quadratic equation</h3>
Given the quadratic equation below
f(x) = x^2 - 3x - 4
Factorize
f(x) = x^2 - 4x + x - 4 = 0
f(x) = x(x - 4) + 1(x - 4) = 0
(x+1)(x-4) = 0
Hence the factors of the trinomial to the given quadratic expression are (x+1) and (x-4)
