Your in High School, you should know quadratic formula; start by subtracting 7 from both sides making it 4x^2 - 12x -7, now solve it using the quadratic formula.
Answer: X= 7/2
X= -1/2
Answer:
x=-2, y=1
Step-by-step explanation:
To solve a system of equations, you set x+3 and 2x+5 equal to each other and solve. This simplifies to x=-2. Then you plug itin to one of the equations to get y. Hope this helps and have a magnificent day!!!!! Stay safe!!!
If x₁ and x₂ are solutions of the quadratic equation, then we can write it in quadratic factorization:
a(x - x₁)(x - x₂)
We have x₁ = 5 and x₂ = 7
(x - 5)(x - 7) = (x)(x) + (x)(-7) + (-5)(x) + (-5)(-7) = x² - 7x - 5x + 35 = x² - 12x + 35
<h3>Answer: x² - 12x + 35 = 0</h3>
