Question

if a and B are the roots of 4x2+3x-7=0.... That a and B are alpha and bita​

Answer 1

Answer:

$\alpha \ and \ \beta \ are \ +1 \ and \ -7/4$

Step-by-step explanation:

$Given \ quadratic \ equation,\\ 4x^2+3x-7=0 \\\\ Let's \ find \ roots \ by \ factorising, \\\\ => 4x^2+3x-7=0 \\ => 4x^2-4x+7x-7=0 \\ =>4x(x-1)+7(x-1)=0 \\ => (x-1)(4x+7)=0 \\\\ \implies x-1=0 \ ; x=+1 \\ \implies 4x+7=0 \ ;x=\frac{-7}{4}$

+1 and -7/4 are the zeroes of the polynomial.
