Question

If a + 7/4 = 2, then find the value of 4a² + 1​

Answer 1

Answer:

a+7/4=2

a+7=8

a=1

4(1)^2+1=5

Answer 2

finding the value of a and then substituting and finding the final value

Step-by-step explanation:

GIVEN

• a+7/4=2
• a=2-(7/4)
• a=((2*4)-7)/4
• a=8-7/4
• a=1/4

• now 1+4$a^{2}$=1+4*(1/4*1/4) = 1+1/4 = (4+1)/4=5/4

• therefore value of 1+4$a^{2}$=5/4.
